Copy / paste in Firefox randomly broken

[Julien Olivier]

Most of the time (but not always), when i copy content from an application (for example Gedit) to Firefox, the pasted content doesn't match what was copied. If I then try to paste in another application, the right content is pasted.

I have to copy / paste the same content several times before the right content finally gets pasted to Firefox.

BTW: I found this bug report, but it's closed: https://bugzilla.mozilla.org/show_bug.cgi?id=1438136

[Olivier Tilloy (osomon)]

That upstream bug sounds indeed similar to the problem you're observing, but given that it's closed, it's unlikely to receive attention. Can you file a new upstream bug report and share the link to it here?

[Julien Olivier (julo)]

Sorry, my bugzilla.mozilla account is disabled, and i have no clue why, so i can't open a new bug. I'll do it as soon as my account is back (if ever...).

[Julien Olivier (julo)]

After further investigation, the bug is in Gedit (or GTK?), not in Firefox: I have noticed that, when the bug occurs, I cannot paste (the data copied from gedit) in LibreOffice either. If I close gedit and open it again, I can copy / paste from Gedit to Firefox (or LibreOffice) again.

[Julien Olivier (julo)]

Should i open a new bug, or can you update this one to reflect this?

[Olivier Tilloy (osomon)]

I have updated the affected package.
