Description moli 2014-05-03 02:13:08 UTC
Hello,
i'm newbie here, so i dont know the usual procedure yet.
I've filed a bug at debian-bts with reportbug, but noone reacted, so i had a hunch kde has a separate bts, that's why i'm writing here.
So please take a look at https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=746316 and reply there or move case the here, as you prefer.
Thanks

Reproducible: Always

Steps to Reproduce:
1. make the system to have something to update
2. put "system updater" to the "system tray" and either wait 6 minutes or click on the "system updater" yourself
Actual Results:  
the plasma-desktop crashes.

Expected Results:  
not to crash :)

i removed a whole lot of packages from the default packages after install.

Do you also get this crash when not installing the "system updater"? This seems to be a distribution-specific component.

it's "software updater", SORRY, i mistyped this the whole time in my
first email.
I dont know the package name of the "software updater", i could not
detect it from the process list, sorry. It's debian-kde.

I dont know if it's the same bug, but i can confirm i can reproduce bug
334188 any time at my will.

Yes, it seems to be the same bug, and the cause is explained in bug 334188. Debian testing already "fixed" it by pushing out the newer version of apper: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=746702

What I don't understand is, whether it's normal for Debian to push packages which break ABI (i.e. libappstream0) to the testing repo without pushing all dependent packages together. I'd consider that to be improper.

This is really Debian bug, not KDE one.

My only remaining question is: why does the plasma-desktop crashes when any of the widgets crashes?

Yes, that's a good question. I'd consider such architecture to be too fragile. That's a more generic question than the scope of this bug though.

They need to share a process, otherwise you could not mix them into a single panel or desktop element. If you feel the need to run a single applet in a separate context (which means a separate process, as well as a separate window), use the "plasma-windowed" command.
