0.99.7 Linux: Crash with videos' info panels

Posted: Wed Mar 23, 2022 7:25 am

XnView: MP 0.99.7- 64 bit
OS: Arch Linux 64bit

With all the options except "Preview as tab" selected for the Info panels, I get this crash when looking at a video file in the browsing mode:

Code: Select all

############################################ InfoPropertiesView

Create Tree : File
Create Tree : Video
Create Tree : Audio


############################################ InfoPropertiesView

Create Tree : File
Segmentation fault (core dumped)
code 139

With the Preview disabled under Info panels, XnView crashes on the second selected video file instead of the first one, and the error message is now more like this:

Code: Select all

### ThumbLoaderThread :: setFirstItemToLoad
 ** start condition wake one 3
### ThumbLoaderThread :: setFirstItemToLoad ok
######### CategoryModel :: checkAndSave()

############################################ InfoPropertiesView

Create Tree : File
Create Tree : Image

for a webm file and like this:

Code: Select all

############################################ InfoPropertiesView

for a mp4.


When everything under Info panels disabled, I can select video files without crashing.


Effect: XnView crashes

To reproduce:
1. Browse a folder with video files.
2. Select first video file.
Actual behaviour (bug): XnView crashes :bug:

Expected behaviour: No crash and information in the Info panels is displayed.

Some extra info. The way it crashes is freezing for like two seconds and only then crashing.

I would have ran it through gdb or something, but XnView seems to open through a script, and the binary /opt/xnviewmp/XnView complains about missing libraries.

I noticed that there's something akin to my problem described in this thread.

I tried the mentioned settings videoMode=false and videoMode=true, but I don't think they mattered for me, or I'm not putting them in the correct place. That's a possibility too.

I did manage to run XnView through gdb with the command:

Code: Select all

LD_LIBRARY_PATH="/opt/xnviewmp/lib:/opt/xnviewmp/Plugins:$LD_LIBRARY_PATH" QT_PLUGIN_PATH="/opt/xnviewmp/lib:$QT_PLUGIN_PATH" gdb /opt/xnviewmp/XnView
Here's the backtrace. No debugging symbols unfortunately, though.

Code: Select all

you close the preview, and you have the crash?

I'm saying that the crash happens whether or not the preview is active. It's just that it requires going to look at two videos instead of one until it crashes if preview is ticked on for the info panel.

Curious, does it also crash when you use xnviewmp-system-libs?

If it works fine with xnviewmp-system-libs, then it might be due to a mismatch of Qt libraries with xnviewmp versus an updated Arch system?

The reason I do not use xnviewmp-system-libs is because it seems to have stability issues compared to xnviewmp.

It doesn't crash when using xnview-system-libs.

This makes me believe it's a mis-match between your Arch's system Qt libraries and the ones that come bundled with XnViewMP (the default xnviewmp package.)

This has been a recurring issue with XnViewMP and Arch-based distros. :(
