Patch fixes the problem ok but it shows another small flaw in our
ErrorReporter. When crashing with a long "problemData" string the other
interesting fields like "Error object:", "Version: " and "Trace: " are
not written. See below. Please write a follow up bug for fixing that.
Suggested solution is to either truncate the string to a more sensible
length or maybe we should abandon the fixed size length of these error
messages(which we have implemented in order to avoid filling disks with
logs) and instead go for a max length of the error log.

Suggested fix:
make log message bigger
