Comment 6 for bug 956282

Testing on OS X 10.7.5:
- reproduced with the official stable package 0.48.2 (same console messages),
- not reproduced with local builds (stable 0.48.2 and later, trunk)
- not reproduced with new (experimental) application bundles based on the 'osxmenu' branch.

On OS X, the problem turned out to be missing poppler encoding data files [1]:
1) they are not included in the (dated) application bundle; and
2) if included, they need to be made known to the (relocatable) inkscape binary.

With Windows builds, possibly poppler-data is outdated, or not found by the inkscape binary (could be that full relocation support for poppler on Windows was added in a later version than the one included in the stable devlibs (poppler 0.12.1).

Fix used for a relocatable application bundle (WIP) on OS X in rev 12635-12638:
