Application: dolphin (17.04.2) Qt Version: 5.6.2 Frameworks Version: 5.32.0 Operating System: Linux 4.4.92-31-default x86_64 Distribution: "openSUSE Leap 42.3" -- Information about the crash: - What I was doing when the application crashed: I was trying to save some attachements from an eMail. - Unusual behavior I noticed: Lately, I realized that depending where I work with my notebook (which location / network) I have big problems from different applications to access the file system (open or especially store files) - Custom settings of the application: I have set autofs. So depending if I work in the office (to access NAS, Server, etc) or at home office (NAS) or on the road (eg at girl friends place) with no external storage. That was working fine for the last almost 2 years. But in the last weeks, I got big troubles. It often takes a long time (up to minutes) to open the file save dialog. And it takes long again, when changing directories. This problem occures much more, when out of the office where I utilize the system most (Thought: There might be stored paths in the "last used files" section, which are not accessable, when not in that network.) -- Backtrace: Application: Dolphin (dolphin), signal: Segmentation fault Using host libthread_db library "/lib64/libthread_db.so.1".

Problem further narrowed down: autofs and KDE-FileDialog When away from network any app using standard KDE-FileDialog is hanging for a long time. Every change in directory tree is then starting long hanging again. Reproducable: Always - Go away from network with most used autofs drives - Us file open or store on any app using KDE-FileDialog As soon as autofs is stopped (systemctl stop autofs), problem goes away. => so it is a combination of autofs with KDE-FileDialog. Partial work around: - LibreOffice: Change preferences to use LibreOffice Dialogs - Thunderbird + Firefox: Remove kmozillahelper from system (However, with any update it is re-installed again) However, other apps using KDE-FileDialog still affected.
