Crash when rotating circle with offset rotation center.

[Tavmjong Bah]

Inkscape crashes after one or two seconds of rotating a circle with an offset rotation center, next to another circle.

Warning: This can hang-up your system. On Linux I needed to open new session via Alt-Ctrl-F3 to kill the process.

To generate crash, rotate the right-most circle in the attached SVG file using the rotation handles around several times.

Inkscape 0.91+devel r14527

[su_v (suv-lp)]

Reproduced with Inkscape 0.91+devel r14527 on OS X 10.7.5.

Based on tests with archived trunk builds:
- not reproduced with 0.91+devel rev <= 14409,
- reproduced with 0.91+devel rev >= 14411;
this regression seems similar to the one mentioned in the comments 3-7 of bug #1479167. Turning of snapping to path intersections prevents the crash (tested with current trunk r14527).

Forgot revision number: noticed with r14527, also with glib-hunt branch which was merged with r14520.

seems to be fixed with this patch https://bugs.launchpad.net/inkscape/+bug/1535444/comments/3

[su_v (suv-lp)]

Crash still reproduced on OS X 10.7.5 with patch from bug #1535444 applied to r14955. AFAICT the backtrace is about the same as the one attached in comment #2.

Thanks for try su_v
