Several people including me have reported on the linuxquestions.org
Slackware forum that Wireshark-2.0 crashes (segfault) at startup.

The Qt UI version of Wireshark-2.0.0 will crash on startup for us, every
time. We have different hardware, including both 32 and 64 bit systems. All
of us are using Slackware Linux, but some have the stable Slackware-14.1,
and some are using "Slackware Current" which has more up-to-date packages.
My version of Qt is 4.8.7, but others report the crash with Qt5.  The crash
is immediate, with nothing displayed. Even "wireshark --help" crashes.

Wireshark-1.12.8 works fine on these systems, both Gtk+ and Qt UIs.

Wireshark-2.0.0 with the Gtk+3 UI works also.

Wireshark-2.0.0 with Qt always crashes. Below is a gdb traceback.

Are there any ideas of what we can try?

Thanks for the info, by far the best way to report Wireshark bugs is on the wireshark Bugzilla (https://bugs/wireshark.org).

There have been a few bugs fixed since 2.0.0 was released, so check the bugzilla first for an existing report on the issue.
