Comment 10 for bug 1730241

I just restarted Evolution (but did not reboot my system or make any other changes) and now Evolution is crashing for me in the identical way described here. I literally just quit Evolution, it was running fine, and restarted it and now it just crashes with the same stacktrace shown above, a null pointer passed to g_ascii_strtoull() (will add it as an attachment) after this error:

  (evolution:14770): GLib-CRITICAL **: 19:35:04.237: g_strsplit: assertion 'string != NULL' failed

I'm now a little afraid to restart my system in case more things start to fail.

FYI, glxinfo shows:

$ glxinfo
name of display: :1
X Error of failed request: BadValue (integer parameter out of range for operation)
  Major opcode of failed request: 154 (GLX)
  Minor opcode of failed request: 24 (X_GLXCreateNewContext)
  Value in failed request: 0x0
  Serial number of failed request: 93
  Current serial number in output stream: 94

I think if nothing else, a bug should be filed with libcogl asking them to be more defensive in their programming here and handle badly formatted GPU version string. For example in my backtrace I can clearly see that the strings being taken from the context are all null, and that _cogl_gpu_info_parse_version_string() simply passes this to g_ascii_strtoull() without checking.

I'm running with NVidia proprietary drivers with my old crusty NVidia GeForce 8400 GS with the proprietary driver version 340.107 that I've been using, and has worked fine, for years.
