Bug#906290: kde-full: several KDE applications hang shortly after start

2018-08-16 Thread tdowning 
Package: kde-full
Version: 5:102
Severity: important

Dear Maintainer,

On 14 August 2018 I performed apt-get update; apt-get upgrade.  The last
date of update/upgrade was aprox 3-4 weeks earlier.

Before the 14 August upgrade I observed no bugs other than a minor, infrequent
plasma desktop issue.  After the upgrade, KDE applications no longer operate
normally. 

All KDE apps start, and function normally for a short time. They then cease
to be responsive to either user input, window manager operations, or network
driven input.  Clicking the title-bar 'quit' icon will eventually result in
the "not responding" dialog.

The time the app runs before hang is usually less than one minute, but sometimes
can be longer; rarely more than 15 minutes. Amount of user input does not seem
to correlate with how quickly the hung state occurs.

Not all KDE apps suffer the problem, notable Konsole has operated normally. 
Kmail,
Konqueror, KPat -), are notable apps that suffer the problem.

I have not seen any non-KDE applications have this problem.

FWIW, running KMail from console reveals the message:

QFont::setPixelSize: Pixel size <= 0 (0)

repeated 50-100 times rapidly, while the app is displayed by idle.  After this
KMail is hung.

Please feel free to contact me if I can be of any assistance. I haven't done any
KDE development in years, but I still do C++/linux development.

Thanks
