Taskmanager widget crashes X

[Michael Schuerig]

Repeatedly in the past 10 days (with current Debian/unstable KDE
packages each day), KDE has crashed X on me. The proximate cause has
always been that I clicked on a tab in the taskbar contained in a panel
at the top edge of the screen. Specifically, this happened when I
clicked right at the edge of the screen.

I'm using (unfortunately, but I don't see an alternative) the closed
source nvidia driver. The backtrace info from the log is appended
below, but I it doesn't seem to be very helpful.

I appreciate your ideas and suggestions what might be going wrong and
what to do about it.

 Hi Michael,

 I'm also using closed-source custom-compiled (or linked) nVidia
 drivers on my 2.6.30 kernel (also custom-compiled) with almost
 solely unstable (a couple of experimental packages).

 I've seen X being far more stable than previously - say in the past
 two or three months, I've had very few crashes, perhaps two.  Prior
 to that I was seeing a lot more, not sure if that was X, KDE 4.2 or
 a combination.

 Given you're using a panel on the top of the screen, which is
 likely not where most people run it, would you be able to try it
 at the bottom edge of the screen for a while and see if the problem
 continues?

 I'm using NVIDIA-Linux-x86-185.18.36-pkg1.run - I'm guessing
 you're on that version too?

 Jedd.

I'm using panels at both edges. Pager and Taskmanager at the top edge,
K menu, system tray etc. at the bottom.

Ah, yes, I'm using an older version (180.44-2) of the nvidia driver and
kernel 2.6.29. When I last tried, a few months ago, more recent
combinations of driver and kernel resulted in "drop outs", very short
flickering to a black screen. I'll have to try the current kernel with
current driver.
