Description zendas 2020-04-01 11:21:41 UTC

Application: k3b (18.08.1)

Qt Version: 5.11.3
Frameworks Version: 5.54.0
Operating System: Linux 4.19.0-8-686-pae i686
Distribution: Debian GNU/Linux 10 (buster)

-- Information about the crash:
Today I found two problem when I use K3B:
1. When I installed K3B,then "*.iso" file's default open item will changed to K3B (ok,use K3B burn iso files,no problem),but if I  right click mouse button and select "open" or dbclick left mouse button (the same as open item),K3B will loadding very long time and crash,and I saw my iso file was send to some where's alert?When the iso file were send finshied,then K3B will crash at the same time?
2.The other problem is I found a logic problem that is when I set K3B burning will hide main form's function,when I finished burn process,the main form still hide..so I can't see it again?(but I can see K3B with "top" process,it's not closed,just hided)I'm not sure is this Debian's problem or K3B's problem,because I used this function before,and it's no this problem before,but I'm use gnome desktop before.

The crash can be reproduced every time.

Any chance you could try a more modern verison that is not more than 1 year old?

I'm 94% sure i already fixed this

Created attachment 128191 [details]
The function of hiding the main window is not normal

When I enable "hide main window when burning" function,
and the main window will not be restored after the burning is completed?

Comment 5 zendas 2020-05-06 08:23:26 UTC

I add Debian buster multimedia and backports source,and I upgrade K3b to 19.04.2.
Then open ISO hang problem is fixed.But hide master window when burning function problem is still not fixed.
