  Target Milestone: ---

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.
