Description Cengiz Gunay 2019-12-02 03:48:45 UTC
Application: digikam (6.1.0)

Qt Version: 5.13.0
Frameworks Version: 5.60.0
Operating System: Linux 4.19.60-1-MANJARO x86_64
Distribution: "Manjaro Linux"

-- Information about the crash:
- What I was doing when the application crashed:

I had albums scanned from an NFS drive and clicking on them just freezes DigiKam and all of its operations. 

I'm on Manjaro. I can provide more details/test if there is any need.

The crash can be reproduced every time.

-- Backtrace:
Application: digiKam (digikam), signal: Aborted
Using host libthread_db library "/usr/lib/libthread_db.so.1".

Which kind of database type do you use ? Mysql or sqlte ?

Where are stored your database file ? On the NFS mount path, in local, or in a remote server ?
Comment 2 Maik Qualmann 2019-12-02 07:12:42 UTC
The crash at this point is not unknown. We used a CoreDbAccess here to synchronize the access. Meanwhile we use a QReadLocker. The crash should be fixed in a more recent digiKam version.

Hi, 

I tried to run the 7.0.0 stable from the 64-bit AppImage on the same system, but I'm getting this core dump:

$ ./digikam-7.0.0-x86-64_8da9c2c162c686a1161d2f7525ab3e3b.appimage

I'm not very familiar with AppImage so is there anything I can try?

Try to start Appimage bundle with a preload a library like this :

LD_PRELOAD=/usr/lib64/libxcb-dri3.so.0 ./digikam-7.0.0-x86-64.appimage

Name and path to libxcb can change in different system.

Sorry for not replying to this earlier. I didn't know how to look it up. It's a QSQLITE backend, but it's saved on a local drive, not the NFS drive.

This worked, and I can confirm that I'm no longer getting crashes in the 7.0.0 version while browsing the NFS folders. 

Actually, I tried to track the crash down by running the system-installed version of DigiKam, but apparently it's already upgraded to 6.4.0, which also doesn't exhibit any crashes. It's quite slow because it's constantly scanning the files (it's a large database), but still functions. Also tried ShowFoto 6.4.0 because I wasn't sure if the crash was from there, but it also works.
