New crash information added by DrKonqi

keditbookmarks (4.14.21) on KDE Platform 4.14.22 using Qt 4.8.7

- What I was doing when the application crashed:

After importing bookmarks from Firefox, I attempted to drag the 12 imported folders/parentless bookmarks to the root bookmark directory and the manager crashed. This always happens when I attempt to bulk-move bookmarks or folders, but not if I move single folders.

Dear Bug Submitter,

This bug has been stagnant for a long time. Could you help us out and re-test if the bug is valid in the latest version? I am setting the status to NEEDSINFO pending your response, please change the Status back to REPORTED when you respond.

Thank you for helping us make KDE software even better for everyone!

Comment 3 robert.l.kief 2018-11-02 15:34:36 UTC

When I reported this bug back in 2015, I was still using Fedora.  I'm now using Linux Mint and don't have a computer running Fedora.  I'm sorry that I can't provide any new information. RLK
