error on new tab

[anonymous]

happens every time when i am logged into trac in one tab, open a new firefox tab and go to a quick link for a page that is a custom ticket query. Page fails to load with this error, until I log in to trac twice.

Traceback (most recent call last):

OperationalError: database is locked

From the line numbers you do appear to be running 0.10.4 which should have fixed the issue. I'll echo cboos' last sentiments in ​http://trac.edgewall.org/ticket/4929#comment:8 — are you sure the "login twice" workaround is necessary, or if you refresh the page a couple of times does it come up right?

One of the many "OperationalError: database is locked" errors. No follow-up on this one, assuming an update of SQLite or PySqlite did the trick.
