Package: pinpoint Version: 1:0.1.8-2 Severity: important X-debbugs-CC: pkg-gnome-maintain...@lists.alioth.debian.org
Just running "pinpoint /usr/share/doc/pinpoint/examples/introduction.pin" shows the first slide, and if I just wait or hit a key, I get a segfault. The problem may be in the underlying libraries, but could simply be a case of buffer overflow. This machine uses gtk 3.20, and I could reproduce the crash on one that's still on 3.18. Both are using libxcursor 1:1.1.14-1+b1.
