Oops...
Trac detected an internal error:

Use {{{ }}} around your block for preformatted text.

Got the same error, with trac:trunk [1868], using 'cmd' as the search string (w/o the quotes).

I can't find yet the exact cause of the error: I did not find any other string that produce this error, even if they are 3 character long… weird.

It seems related to search within the Ticket DB (at least with my database). Another term with triggers an exception is 'pol'.

The term has to exist in the ticket DB to make Trac crash.

This problem was hopefully fixed by [1937], please reopen if that's not the case.
