I have no clue how to help them, cause the error message isn't very descriptive.
Maybe add the log in question to the Exception's error message?

are you sure you don't have an export.log?

The log is already part of the exception and included in the crash report. The problem is that MC's ReentrantThreadExecutor doesn't have any special handling for ReportedExceptions (i.e. it doesn't generate a crash erport when it encounters one, it merely logs its stacktrace).
We could probably add our own catch to handle them at
