SUMMARY After upgrading to 19.10/plasma 5.17, Dolphin can't start. STEPS TO REPRODUCE 1. Upgrade from 19.04 (+backports) to 19.10 (+backports, but it was the same without them) 2. Try to start Dolphin OBSERVED RESULT In console: > Error parsing XML document: "unexpected character" at line 115 column 1 Then it crashes. With another user account (a new one created in 19.04), it works fine. EXPECTED RESULT Dolphin starts normally SOFTWARE/OS VERSIONS Linux/KDE Plasma: Kubuntu 19.10 (+backports) KDE Plasma Version: 5.17 KDE Frameworks Version: 5.64.0 Qt Version: 5.12.4 ADDITIONAL INFORMATION I don't know how to get more logs… I have a general (?) MySQL issue in the system, it won't start. Then Amarok and Akonadiserver (and probably some others) can't connect to MySQL and work normally. This is the same for a fresh new user account. It might be related ? I'm sorry if it the wrong place to report this issue (as I'm not sure it's related to Dolphin or MySQL).
> OBSERVED RESULT > In console: >> Error parsing XML document: "unexpected character" at line 115 column 1 Hmm, I think that's unrelated. Can you attach a backtrace of the crash? For details, see https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports

Thanks. It's crashing in KXMLGUIClient::setXML(), which is where it tries to read your customized configuration file. This explains why it crashes for your user but not a fresh user. There appears to be something about the file that it doesn't like. Can you attach ~/.local/share/kxmlgui5/dolphin/dolphinui.rc?
Sure. Here it is: https://vps.lapineige.fr/privatebin/?c2646181dcb90b36#F+fBMSqtFWaG7imAhRtoc8PZ5IBq846lCGWDKLplLJ0= (note: I did not edit this file manually)
Yep, the file is malformed: </kpartgui> o_forward"/> <Action priority="0" name="go_home"/> <Action priority="0" name="go_up"/> <Action priority="0" name="icons"/> <Action priority="0" name="stop"/> <Action priority="0" name="view_zoom_in"/> <Action priority="0" name="view_zoom_out"/> </ActionProperties> </kpartgui> It's not valid XML. I guess something interrupted the process while it was being written. Regardless, this should definitely not make Dolphin crash. That's tracked by Bug 400271. In the meantime, you can safely remove that file. It will reset Dolphin's main window to its default settings, and then you can re-make any customizations you made to it. *** This bug has been marked as a duplicate of bug 400271 ***
Ok, I removed this part so it fixed the XML file (while I didn't lose my custom UI, and the time to rebuild it). Problem solved, thanks a lot :) (Now I need to find out what's my issue with mysql 😅 - but that's off-topic)
You're welcome!
