Inkscape crashed when cutting a polygon from another layer (core dump attached)

[Tom Dignan]

I was using inkscape to draw a pencil from rectangles that I turned into paths. The steps were long and elaborate, so I don't recall them all. This happened more than once. I am on a 64 bit machine. I turned on core dumps so I could at least provide some useful information. I hope it is enough to diagnose the problem.

Thanks!

Please add information about your OS/platform and Inkscape version.

Could you provide a backtrace with gdb instead? If not, a 'steps to reproduce' would be helpful for bug triage.

[Tom Dignan (tom-dignan)]

I got this stack trace by doing gdb `which inkscape` corefile. It
doesn't look helpful to me, but maybe I just don't see it. The problem
occured when using about 7 different layers and trying to cut a
polygon out of one of them. I cannot replicate it, I tried. But it did
happen more than one time while I was working.

Which OS/platform are you using, and which Inkscape version?

You don't have the debug symbols for Inskcape installed. AFAICT no useful information in the backtrace with regard to where the crash happened in inkscape.

Do you remember what tools and (menu) commands had been involved? You can't "cut" something out of a layer in Inkscape - did you select two objects from different layers and used 'Path > Cut' or 'Path > Difference'? Are these objects/paths in any way specially complex (like e.g. huge, with many nodes)? Which tool was active when the crash happened (e.g. select tool, node tool)?

[Tom Dignan (tom-dignan)]

* Kubuntu 10.04 latest
* AMD64

The crash occured when I selected a curved triangle I made, and hit
control + x.
I will try to make it happen again later tonight.

I'll compile the latest with symbols and start working with that one.

Sorry I didn't have more info.

Was the select tool or the node tool active when the crash occurred?

If the crash only happens when cutting (possibly mixed with undo) in the node tool context, the issue might be similar to bug #696732 which no longer occurs in 0.48.1 (fixed with bug #622350?).

See also more recent similar report bug #729416 (crash when using Ctrl-X in the node tool context <F2>).

Closing due to lack of feedback. Available information is not sufficient to further investigate the exact cause of the reported crash. Feel free to reopen if the same crash also occurs with current inkscape versions.
