Small update - while I haven't been able to debug it fully yet, I can 
confirm that there seems to be an issue resulting in a SIGSEGV while 
trying to load the previously stored TDesktop (tried under Win64 and 
x86_64-linux - interestingly not getting RTE101 as reported by Kevin, 
but it might be due to a different target platform and/or different 
version). As far as I can see, our textmode IDE uses different approach 
to restoring the stream which is probably the reason why the issue isn't 
triggered there.
