this is still an issue with 0.11.1-1.
looking into the code, it seems that in block.c the get_tmp_filename function
calls mkstemp, which should hopefully return some sort of error if it can't
create the file. in any case, the get_tmp_filename function should probably
check if the returned file is writeable and issue a different error in that
case...
live well,
