Comment:

 I let Tor repeat this error over and over again and did not stop it as is
 wasn't showing any connectivity/usage problems.

 Today I launched it again and Vidalia logged the errors again, so I
 stopped Tor.

 I went to %APPDATA%\Tor and removed the following files
 - cached-microdescs (The one Tor can't write to)
 - cached-microdescs.new (I saw this file before, removed to have it fresh)
 - cached-microdescs.tmp (I can't remember to have since such a file
 before, removed to have it fresh)

 History
 - cached-microdescs created 2012-05-19, changed 2013-04-28, accessed
 2013-04-28
 - cached-microdescs.new created 2012-05-19, changed 2013-05-05, accessed
 2013-04-28
 - cached-microdescs.tmp created 2013-05-04, changed 2013-05-05, accessed
 2013-05-04

 (So I was correct .tmp was never there before)

 All files shared the same access-privileges.

 I restarted Tor and it created the first two files. No error since then.

 The files created share the same access-privileges and are the same as
 there were before. Since I had not seen this error during the alpha-phase
 of branch 0.2.4.x I change the version to 0.2.4.12-alpha.

 The strange about this issue is that I upgraded from .11 to .12 on
 2013-04-30 and the error appeared on 2013-05-04, never before. Might be
 that it takes Tor some time to gather enough microdescriptors to exhibit
 this.

 I change to "needs more information" and wait to see if it occurs again in
 which case I report back or ask if we can close this ticket otherwise.
