Description Adam Pigg 2009-01-04 21:55:37 UTC
Version:           4.1.85 (using Devel)
Compiler:          gcc 4.3.2 x64 
OS:                Linux
Installed from:    Compiled sources

I have an ipaq pda.  Becasue there is no kde4 software from the synce project yet, i opted to use the gnome tray applet synce-trayicon.

The applet runs on login, and all seems ok.  I then plug in my ipaq, and the applet pops up a message saying it has been connected.  Shortly after, plasma starts to take 100% cpu, and i have to be quick to kill it.

The same also happens in another order.  This time, the ipaq is connected, plasma is running but not synce-trayicon.  I then run synce-trayicon, and it pops up a message saying the ipaq is connected.  This time, plasma runs ok, until i unplug the pda, at which point i get a message from the applet saying it was disconnected, and plasma starts to take up 100% cpu.

Options for surviving a reboot are:
1. Be quick and get to konsole to kill plasma
2. If 1 fails, alt-sysreq-r alt-f1, login and kill plasma
3. If 2 fails, hard reboot :(

Sorry, im wrong to blame synce-trayicon as the problem also occurs when it isnt running, and the ipaq is (un)plugged.  Could possibly be network related, see the attached output from strace.

find me on irc and i'll start feeding you patches to experiment with =) it'll be faster if we do this one in "real time".. basically we need to start putting some output in the x11embed* classes and see where we are going around and around...
