Christophe, thanks for your suggestion. I don't want to sound ungrateful or
harsh, but I asked what causes the incidence to be 0 (null) in the code. I'm
well aware that I can ask the backport of this commit to my distribution, and
it was not what I asked. I already went through this path before and from my
experience this will take a few weeks to get processed at best (perhaps a month
when 4.6.3 will be going out). And due to this very reason, they may just
ignore or reject the request as unimportant, since this seems to only affect a
few users. But this bug affects me now, and I'm willing to do something to fix
my problem now.

I want to know what is causing this situation on my configuration, because I
presume there is something I can do to fix it on my side to avoid the code path
that is causing the bug. It is certainly something that doesn't affect many
users and has a very specific trigger, otherwise KDE developers themselves
wouldn't release two versions (4.6.0 and 4.6.2) with so blatant crashes. I also
verified with a new user (with a blank KDE profile) that the crash doesn't
happen.

So there is certainly something in my KDE configuration, something among the
56,280 files and directories residing inside my ~/.kde/ directory (that are
accumulating since KDE 2.0), that triggers this for me (and a few other users
who also reported this issue).

I already straced plasma-desktop and the file accesses before the crash don't
tell much. Instead of shooting in the dark I would like to ask the developers
watching this report, who are much more familiar with KDE internals, what may
be causing this situation. And take this opportunity to clean up some of the
cruft accumulating in my configuration and in my ~/.kde/ .
