Description Natalia Portillo 2018-12-15 23:30:13 UTC

Application: elisa (0.3.0)

Qt Version: 5.12.0
Frameworks Version: 5.53.0
Operating System: Linux 4.19.8-arch1-1-ARCH x86_64
Distribution: "Arch Linux"

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

Opened the application, saw a dialog saying that Baloo prevented it to watch the folders, chosen to modify Baloo.

From then on, it crashes on every load.

The crash can be reproduced every time.

-- Backtrace:
Application: Elisa (elisa), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".

Running with strace could reveal which file causes the taglib extractor to fail.

Comment 2 Matthieu Gallien 2019-05-02 20:50:12 UTC

Should I move this report to KFileMetaData as I do not plan in the close future to modify Elisa such that a crash in the extractor would not crash the application itself ?
