Testing on OS X 10.7.2:
- Not reproduced with Inkscape 0.48.2: saving as (or saving a copy as) fails and displays an error dialog, but does not crash. Console message:
** (inkscape:88244): WARNING **: Unable to find output module to handle file: /Users/su_v/973174-save-as-JPEG-1.jpg

- Reproduced with Inkscape 0.48.3.1 and 0.48+devel r11146

> - Reproduced with Inkscape 0.48.3.1 and 0.48+devel r11146

More tests with archived trunk builds indicate that the regression was introduced between r10819 and 10828 (lp:inkscape):
- not reproduced with <= r10819
- reproduced with >= r10828

Possibly a side-effect of the fix for the win32 saving regression in 0.48.2 (r10820, r10821)?

Full backtrace (Inkscape 0.48+devel r11150 debug build, 64bit, OS X 10.7.2) attached.

great bug hunting information! (bug introduced by me in r10821)
fixed in rev. 11158

[Kris (kris-degussem)]

Backported for inkscape 0.48.4 in 0.48.x branch revision 9894.

I have a similar problem when using "Guess from extension" to save an SVG file - inkscape crashes out. Would this have been fixed by this bugfix?

[Launchpad Janitor (janitor)]

This bug was fixed in the package inkscape - 0.48.4-0ubuntu1
