(příště prosím anglicky, klidně stačí přes Google Translate. Ne všichni vývojáři kteří čtou bugy umí česky :-)

Díky za report, bohužel v tomhle nevidím nic, co by nějak přímo souviselo s kódem v KMailu. Může to být chyba v Qt4 nebo KDE4, kterou už neopravíme, protože to jsou nepodporované verze. Ta chyba vypadá, že je kvůli ikonce KMailu v systray, ale v Plasmě 5 už je systray implementovaný jinak, takže tenhle pád tam nastat nemůže. 

//

Unfortunately nothing seemingly related to KMail code, could be something in Qt4/KDE4 code that's not gonna be fixed as both are no longer maintained.

QETWidget was used for XEmbed widgets, which is how systray was implemented in KDE4 - I suspect that something went wrong there and caused us to crash due to our systray icon. We don't use that mechanism at all in Plasma 5, so I guess there's no point investigating further.
