Had you been working with files from a removable media (opened from / saved to) last time, and this meia (e.g. USB stick) is no longer present on your system?

1) The MRU list (managed by GTK+ itself in 'recently-used.xbel' and shared with other GTK+-based applications, e.g. GIMP) is checked for the presence of related bookmarked files, and entries not found on the current system are omitted from the sub-menu in Inkscape. This check can trigger an attempt to access to a no longer present removable media.

2) Inkscape's file dialogs remember the last used locations (directories) and try to open them the next time used, and could also trigger an attempt to access a no longer present removable media.

Alternatively, if the Windows error dialog does is not triggered due to having worked with files from a removable media, it could be related to

Thanks ~suv. The following suggestions worked

I can confirm this bug under Windows Terminal Server 2008.
The file .recently-used.xbel contains references to no longer existing drives (unplugged USB sticks or a card reader with card removed) AFAIR it is stored in C:/Users/USERNAME/AppData/Local/Inkscape. Deleting the file causes the error to go away, but it is no permanent fix. The bug reappears from time to time and can be worked around each time by deleting the file.

Let's see where this could be fixed.

Inkscape uses GtkRecentManager for the recent-files menu.

inkscape-0.48.4/src/interface.cpp line 974:
    gtk_recent_chooser_set_show_not_found (GTK_RECENT_CHOOSER(recent_menu), FALSE);

(some steps inbetween, not really interesting)

gtk+-3.4.2/gtk/gtkrecentchooserutils.c line 468:
    if (!show_not_found && !gtk_recent_info_exists (info))

gtk+-3.4.2/gtk/gtkrecentmanager.c line 2044 and before:
in function gtk_recent_info_exists:
      if (g_stat (filename, &stat_buf) == 0)

glib-2.38.2/glib/gstdio.c line 496:
in function g_stat:
     retval = _wstat (wfilename, buf);

_wstat is the Win32 API Call, on which the pop-up error arises (AFAIK).

The MSDN forum people say that this pop-up error message can be disabled by SetErrorMode

I have no idea about building inkscape under Windows. I assume that this line of code should fix the problem, but I'm not sure where the line should be placed.
setErrorMode(SEM_FAILCRITICALERRORS | SEM_NOGPFAULTERRORBOX | SEM_NOOPENFILEERRORBOX);

A partial workaround would be changing the internal setting that the recent-files menu does not check if files still exist. But then this annoying message would still appear at other places (just search the bugtracker for "no disk")

inkscape-0.48.4/src/interface.cpp line 974:
    gtk_recent_chooser_set_show_not_found (GTK_RECENT_CHOOSER(recent_menu), FALSE);
-> change to TRUE

I found a fix, just one line in main.cpp. Patch is attached.

how to test the bug in a VM:
-winXP virtualbox VM
- add a floppy drive, insert a (virtual) floppy, format it. If you need a floppy image, use this: http://www.codehosting.net/blog/files/blank.img and format it
- Open inkscape (I built from latest trunk myself, should be the same with regular version)
- add some text/element
- save file to floppy
- Close Inkscape
- eject floppy
- reopen inkscape

Patch tested successfully on Windows XP, Inkscape trunk revision 12865.

Committed in the trunk, revision 12866.
Thanks for the patch, Max!

if that helps: The same fix as before also works for the 0.48.x series (patch attached). On some systems this bug can get really annoying, I had to click away about 10 such messages at every inkscape start.

Fix backported to the 0.48.x branch, revision 10008.
