  Usually a very short debug session is needed. If there is a loop pattern
you will spot it quite fast, accumulating megabytes of logs does not help.
Looking at the beginning of the output where gam_server tells what client
are here, what they are watching is usually what is needed to get some 
ontext on the following output.

  So kded watch the error output

  Okay you have a loop over. 
Very first thing would be to tell the KDE environment to not watch 
.xsession-errors to avoid the loop.

  I never use KDE, can you get some KDE developpers to debug the FAM request
they are doing ? The invalid length error was supposed to be fixed. Did you
run clients who were using an old gamin library ?

  Not to me, to the KDE guys I guess. This kind of policy should not be
buried in the code, that could go in the user configuration file though.
