I get a crash with a similar stack trace when moving focus in the window in certain ways. It's very easy to reproduce for example by starting Qalculate and pressing the tab button twice. Does the crash you're experiencing happen under similar circumstances?

At least the crasher bug I've noticed has apparently been fixed upstream in the latest release (0.9.6). The changelog for that upstream release includes "Fix crash when expression entry reclaims focus if compiled with optimizations (GTK+)". I don't know if that's exactly the same bug I've experienced, but the cause may well be the same, and the crashes don't occur with the upstream 0.9.6 source.

The patch attached in the following upstream bug also seems to fix the crash when applied to the 0.9.4 source in Feisty:

The version of Qalculate in Gutsy is still 0.9.4 so this may very well also affect Gutsy.

There's also a similar report[1] in the Debian BTS, probably about the same bug. There's also a patch attached there.

Fix released because 0.9.6 is now in hardy. Linked debian bug is now fixed too.
