Thanks for reporting this bug, in order to make Ubuntu better & improve the Linux-Experience overall.

Upstream duplicate:
https://bugs.kde.org/show_bug.cgi?id=355449 (Plasma crash when trying to configure online account for telepathy)

Looks like it's solved in KDE-Applications 15.12 – Sorry, for not having better news.

But, you can still asign to to bug 1547571 with "Does this bug affect you?" -> "Yes, it affects me, too"

In order to make this upgrade happen, support is welcome.

[Patrick Carabin (patricarbel)]

The program systemsettings5 displays very badly the informations, and impeaches to change some:
it imposes the size of frames in a manner so that i cannot see what i could change ( e.g., the keys to walk through the different Bureaux it displays the Ctrl-F1, but the place where i have to type the new keys is UNDER THE FRAME, so it's IMPOSSIBLE to change it. Please, REMOVE THE DIMENSION LIMITATION, so it can display on ANY SCREEN, without the assumption of a SPECIAL SIZE. That assumption has NO INTERREST, and can only annoy people. TIA. Patrick Carabin.

[Scarlett Gately Moore (scarlettmoore)]

This bug is very old, if it is still an issue please update the bug with info from a supported release.
