After this, I also could not reproduce the problem on a copy of the Mailbox, which I produced using cp -rl. Probably I should not have used hardlinks there. So this sounds like a chaching-related problem to me? Hm, I remember I renamed the virtual folder yesterday (in the filesystem, using mv).

[Dovecot] SIGBART/SIGSEGV while SELECTing virtual folder
Hello!
I just installed Dovecot's latest nightly build (20081020) and tried the
virtual folder features. I started with a really simple all folder:
| # virtual/all
| *
|all
But selecting this folder causes dovecot to panic (in most cases).
While trying to debug this, I got slightly different results and I am
not really sure yet if this is just non-deterministic, depends on some
cached dovecot data or if there is some difference between the debug
build or my rudimentary, unpatched debian package (which lacks the debug
symbols).
The results below are from a build with --prefix set to a clean,
temporary directory. Similar problems occured also with the alpha2
release, which caused me to try the latest nightly build.
