The bug is already reported here: https://github.com/QtCurve/qtcurve-gtk2/issues/3 Here's my solution: In gtk2/style/qtcurve.c line 375 if detail is NULL the check strcmp(detail, "checkbutton") != 0 ) will segfault. I solved by testing it for not being NULL before checking: https://gist.github.com/anonymous/8e6e4ea32dabf03cf630 Cheers Reproducible: Always Steps to Reproduce: 1. Exec inkscape 2. Play with it for a while with qtcurve is set Actual Results: Freezing occur Expected Results: Work as expected
