Description
If the conf directory is read-only, trac goes into an endless recursion. The only thing visible on the command line is:
Exception RuntimeError: 'maximum recursion depth exceeded' in <bound method AtomicFile.rollback of <trac.util.AtomicFile object at 0x7f166c897c10>> ignored
This is because self._file in AtomicFile is declared after mkstemp and because __del__ is an alias for rollback(). If mkstemp fails, self._file is undefined, causing an endless recursion in rollback which tries to access this variable.
The solution is to add 'self._file = None' before mkstemp.
This problem is present in 0.11 and 0.12 - however we had a couple of user reports so I would like to see the fix also for 0.11.7.
Thanks to Sergey for reporting/diagnosing the issue.

Replying to Felix Schwarz <felix.schwarz@…>:
Can you please merge the fix in trunk as well?
Sure (normally I merge in batches). Done in [9276].
Issue and patch verified, applied in [9263]. Thanks!
(OT: It's always the same. Within a few hours of making a release candidate available, we get a new bug report that should be fixed for the release. Oh well… We probably really should release more often.)
