Hi,

Since I upgraded from 5.1.1 to 5.1.2, the three named components just keep crashing. I already tried deleting my configuration file.

Code: Select all

Application: kded5 (kded5), signal: Segmentation fault

I'm running Qt 5.4.0 and kde-frameworks 5.5.0 on Gentoo

Just a question, did you also update your Qt version?

I updated from Qt 5.3.2 to Qt 5.4.0 4 days before, 5 days ago. Do you think I'll have to recompile KF5? All other KF5 and Qt5 applications work fine.
Plasmashell always crashes when I hover the panel, and sometimes when I hover icons on the desktop. It does not crash as much when I don't do anything with it.

edit: I just realized that I updated kde-frameworks together with Qt, so it should be compiled against the new Qt. But I don't think I have restarted my session since.

edit2: I just fixed it. The hint with Qt pointed in the right direction. the Plasma framework needed to be recompiled without opengl support since another component required me to enable gles2 for qt, which caused problems with the Plasma framework.

Also the KF5 frameworkintegration plugin needs to be rebuilt against the newer Qt version. This is because by design it needs to use private API, which means that it will need a rebuild every time it changes.
