                OS: Linux
            Status: UNCONFIRMED

Hello,

we have been reported in [Latte Dock team -
https://github.com/psifidotos/Latte-Dock/], (that is a panel manager based
totally on kde and plasma technologies that lives outside plasma) for a very
rare crash from this applet when the user clicks on it. 

Because it is very rare the user hasnt managed yet to produce a backtrace. By
investigating the applet's code I noticed the following series of events that
could create this:

when the user expands the applet a:
sessionsModel.reload(); is called,
during that time this model is painted in the main ListView,

could it be that ListView painting hasnt been protected and tries to paint an
item that has been removed from the reload function ?

regards,
michail
