[Kde-bindings] Kde Application becomes unresponsive

[Han Holl]

Hello

I have an application that shows photographs on the root window, and includes 
a small toolbar to go back and forward, pause, change the caption, and such.
The application starts life in the systemtray.

There are two different (?) problems:

1. At (for me) unpredictable moments the application becomes unresponsive. If 
I trace it, I see that there is heavy mouse-over activity and I can see the 
responses to mouse clicks, but signals are no longer delivered to slots. I 
can also see the timer events, every 13 seconds.
 I have a fair amount of STDERR output running in a konsole window and nothing 
is happpening any longer in the ruby part of the program.
Questions: what could cause a process to enter such a state ? And what can I 
do to further debug it. Is there a KDE or Qt debugging stream I could switch 
on ? This might of course well be a programmer error, but what I can't see is 
what kind of error I must make to enter such a state.

2. The only way to quit the program is through a right click in the system 
tray icon, and then to choose quit. Occasionally I get the question:
Are you sure you wnat to quit xxxx,
where xxxx is completely random garbage. Nothing bad happens, but I wondered 
if it might somehow be related.

Cheers,

Han Holl
