exception when modifying issue type

[anonymous]

I tried to edit an issue type of an already existing issue to a new issue_type and got an exception that claimed it was unable to open the database file. There was no actual problem with the database file as I was able to view existing tickets and even create new ones.

I was using Trac 0.9.5 with sqlite 3.3.5 running under Apache 2.054 and Python 2.3.5 using cgi on Win2K sp4

Trac detected an internal error: unable to open database file

When you say "edited the issue type", did you do that using Trac or directly on the database, using sqlite3.exe?

Using Trac through the web UI, the traceback came directly after the attempt.

Looks like a duplicate of #4007.
