[Linux GUI] App crashes while selecting AAC quality level

Post by mod16 »

The application constantly closes/crashes if I want to select a quality level for AAC VBR.

What exactly happens:
1.) Edit the track settings (AAC FDK encoder already selected or select it)
2.) Click on "quality" for setting VBR quality
3.) Click on (still greyed out) icon for quality level selection
3.) Slider appears, but can't be slided/used/moved in any way
4.) Click on "bitrate" in the background (dialog window) to escape the situation (but slider still won't close)
5.) Click on drop-down-menu to choose constant quality - it "opens" (but graphics are bugged, see screenshot)
6.) After 1-2s app closes without GUI error messages

Console shows:

Code: Select all

[...]
(null): ghb_check_dependency() AudioTrackBitrateEnable
(null): ghb_audio_list_refresh_selected ()
(null): ghb_audio_is_passthru () 

Segmentation fault
Activity log just stops (no error messages).

If not reproducible on other systems: Maybe related Ubuntu/Unity 14.04 libs (which I'm still using)?

I also recall having repeatedly the problem, that the slider appeared somewhere else on the screen (above the actual app main window). Maybe this is related somehow, maybe not...

Constant quality selection works fine (as it did before).

What version of gtk are you using. I'm on fedora 21 with gtk 3.14. In some earlier versions of gtk, I experienced odd crashes related to sliders. I think it was version 3.12. At the time I could consistently reproduce a crash by first clicking on a combo box, then clicking on a slider. Any combo box fillowed by any slider provoked a crash in gtk.

I'll load up a Ubuntu 14.04 vm when I have a bit of time and see if it's reproducible there. But I can't reproduce it currently here.

Forgot to mention, I just worked around it by *not* clicking on the slider and instead, hovered over the slider button and used the mouse scroll wheel to to change the value.

I also tried to use the mouse wheel, but the slider is frozen solid.

Tried it on my laptop (also running Ubuntu 14.04): Same issue.

GTK version seems to be an older one:

Code: Select all

$ dpkg -l libgtk2.0-0 libgtk-3-0
Desired=Unknown/Install/Remove/Purge/Hold
| Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend
|/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad)
||/ Name           Version      Architecture Description
+++-==============-============-============-=================================
ii  libgtk-3-0:amd 3.10.8-0ubun amd64        GTK+ graphical user interface lib
ii  libgtk2.0-0:am 2.24.23-0ubu amd64        GTK+ graphical user interface lib
Maybe other users using 14.04 can confirm this.

(At least for me it's not really an issue, just wanted to report it.)
