As reported by karlp on IRC, PV segfaults e.g. if a Saleae Logic16 is used, but the firmware files cannot be found or accessed. PV will show the Logic16 and allows pressing "Run", which then segfaults (confirmed by me as well): karlp@terox:~$ LD_LIBRARY_PATH=$HOME/.local/lib gdb pulseview GNU gdb (GDB) Fedora 7.10.1-31.fc23 Copyright (C) 2015 Free Software Foundation, Inc.

Fix is here: https://github.com/abraxa/pulseview/commit/00420ad511dc298d476a8a9a9cab3c91d3b67e9b
Oops, forgot to update the title of the commit as I kept the title of the first attempt that didn't work. Here's the same commit with the correct title: https://github.com/abraxa/pulseview/commit/1560e15f95dea801d557995f82b5a2969c9c2d38
Fixed in 7e0c99bf95836c89574b53ae3fa7840e2ddca77d, thanks!
