Package: plasma-workspace
Version: 4:5.3.2-2
Severity: grave
Tags: patch
Justification: renders package unusable
Dear Maintainer,
since yesterday's upgrade of plasma-workspace, it's not possible for me to
start a plasma-session.
plasmashell crashes immediately (see attached krash output [1]) with a segfault.
There seems to be a problem with creating a new PlasmoidTask:

Since my /var/log partition resides on an tmpfs, I can't provide any
information of other package
updates on the same day.
After having a look to the PlasmoidTask ctor in plasmoidtask.cpp, I saw that
the m_applet reference,
which is retrieved from the PluginLoader with loadApplet, was dereferenced in
line 57. But a few
lines later the reference is checked for not null.
I created a patch [2] which moved the not null check right after the assignemnt
of m_applet,
this allows me to start my plasma session again.
This patch makes plasmashell more robust, but it seems not to be the root cause
of the loadApplet
not working correctly.
hth, regards
Michael

Description: Fix: dereference-before-null-check
The instance m_applet was dereferenced (which can be NULL if loadApplet fails)
a few lines before a NULL check to m_applet is done. Moving the NULL check before
the dereference to avoid crashing plasmashell.
