Running "kdialog --yesno test" behaves correctly.

When this occurs I have to manually kill my session and log back in again.

Have you installed the Grand Update (See the last three posts, from 5 till 14 May, here http://blog.mageia.org/en/ )?

If so, do you still hit this bug after having logged out and back in?

Comment 3 Simon Rowe 2018-05-18 08:41:34 CEST
Yes, all the latest updates applied. I didn't log out after the latest which just included Firefox (but I'll have to now).

I've been experiencing this ever since upgrading to mga6, never occurred with an older release.
Comment 4 Simon Rowe 2018-05-18 08:43:49 CEST
My hunch, for what it's worth, is that something dies/fails after chrome consumes vast amounts of memory.

Are there any logs that would be useful to capture?
Comment 5 Aurelien Oudelet 2020-08-16 17:15:25 CEST
Mageia 6 changed to end-of-life (EOL) status on 2019-09-30. It is no longer 
maintained, which means that it will not receive any further security or bug 
fix updates.

Package Maintainer: If you wish for this bug to remain open because you plan 
to fix it in a currently maintained version, simply change the 'version' to 
a later Mageia version.

Bug Reporter: Thank you for reporting this issue and we are sorry that we 
weren't able to fix it before Mageia 6's end of life. If you are able to 
reproduce it against a later version of Mageia, you are encouraged to click 
on "Version" and change it against that version of Mageia.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a more recent
Mageia release includes newer upstream software that fixes bugs or makes them
obsolete.

If you would like to help fixing bugs in the future, don't hesitate to join the
packager team via our mentoring program [1] or join the teams that fit you 
most [2].

Issue reduced in frequency when I switched to Firefox. Not seen the issue with mga7.
