musetup aborted while saving config

[benke]

Will try to explain.

There's buddy added from museeq into buddy list and comment for this buddy is added as "Slágerrádió". In config.xml comment is written as Slágerrádió. Later when I tried to save some changes from musetup into config.xml, musetup aborted and config.xml get corrupted. It breaks right in place where comment should be written and museekd cannot be started.
