Please re-test with an up-to-date PV version. PV is trying to show an error message box (for reasons unknown) and Qt isn't having any of it. Adwaita is involved, so no idea if it's a Qt or Adwaita issue.
excuse me, how much more up to date do you want? I _included_ the git version here for you, so you could know what version of code I was using, is there wiki formatting or something so I can bold it for you? karlp@beros:~/src/sigrok-playground/pulseview (master)$ git pull --ff-only Already up-to-date. karlp@beros:~/src/sigrok-playground/pulseview (master)$ git describe pulseview-0.3.0-630-g2a09e77 karlp@beros:~/src/sigrok-playground/pulseview (master)$ git log commit 2a09e77148279258c347f8cf9c55daa667a034f8 (HEAD -> master, origin/master, origin/HEAD) Author: Uwe Hermann <uwe@hermann-uwe.de> Date: Tue Jul 24 22:07:25 2018 +0200 HardwareDevice: Only show non-empty device name components. Fields such as vendor, version, serial number etc. are not always provided by drivers. Avoid printing them, since it causes stray whitespace to be added to the displayed strings.
Similarly to #1265, I can't seem to be able to reproduce a segfault here on my setup (Debian unstable, Linux, 64bit, Qt 5.11.1+dfsg-6, glib 2.56.1-2). $ LD_LIBRARY_PATH=$HOME/sr/lib ~/sr/bin/pulseview -c -l 5 -s [...] sr: [00:06.539995] hwdriver: saleae-logic16: Starting acquisition. sr: [00:06.540050] saleae-logic16: Unable to sample at 100000000Hz with this many channels. sr: [00:06.540104] session: Could not start saleae-logic16 device usb/2-3 acquisition. sr: [00:06.540145] hwdriver: saleae-logic16: Stopping acquisition. Notifying user of session error: "generic/unspecified error" In the UI I'm getting an error popup, but no segfault/crash. Maybe this also hints at a Qt/glib setting that causes some internal asserts() to kill the application or such (?) Not sure. Another thing could be pv/mainwindow.cpp:105, which tries to show the popup, maybe some Qt (or other) bug is causing issues when that's supposed to happen? Might also explain #1265 in that case. Does this happen for you as well with the exact command-line I posted above? Specifically with -c, to forget any previous config stuff? Do you maybe have multiple libsigrok instances around on that system, and it's mixing apps and libs that are not entirely compatible or such? E.g. an older distro libsigrok and a built-from-source newer one? Unlikely to be the problem here, but it's worth double-checking.
Still crashes for me. I did have one run where it just gave the popup and didn't crash, but next run (still with -c) it crashed again. here's the log for it. One thing of note, the log says that it has detected an original salea16. it most definitely is not. This the "noname-xl" board with gregani's bitstreams. karlp@beros:~$ pulseview -c -l 5 -s sr: [00:00.000000] log: libsigrok loglevel set to 5. srd: libsigrokdecode loglevel set to 5. sr:

Do you get "QWidget::repaint: Recursive repaint detected" in #1265 as well? If yes, it's probably the same bug and can be merged.
