Do you remember what you were doing before closing dolphin in this case?

> Do you remember what you were doing before closing dolphin in this case?

Only roughly: I had a cryptomator vault mounted and open in a tab, opened/closed/deleted some files there. Otherwise, nothing specific.

Thanks, do you also have any Bookmarks? You can find them in:
Dolphin hamburger menu -> More -> Go -> Bookmarks -> Edit bookmarks

Asking because the crash seems to have been somewhere in the bookmarks destructor.
Comment 4 postix 2025-02-19 16:46:56 UTC 
> Thanks, do you also have any Bookmarks? You can find them in:
Yes quiet a few. None which are pointing to the mounted folder though.
Comment 5 Akseli Lahtinen 2025-02-20 09:42:55 UTC 
Thanks, I will add some bookmarks myself and see if I can get the crash happen too.
Comment 6 postix 2025-02-25 11:32:39 UTC 
Yeah just happened again, now w/o any mount. Just opened Dolphin and closed it.
Comment 7 Akseli Lahtinen 2025-03-03 12:18:52 UTC 
Can you tell me how many bookmarks do you have?
Comment 8 postix 2025-03-03 12:34:22 UTC 
Currently three: 

* /home/$user/Downloads
* /run/media/$user/$id1
* /run/media/$user/$id2/foo

The last two are volatile usb drives. I think I had created these bookmarks by accident once.
