Nullref Exception when saving a page

[merktnichts]

I'm not sure if it's a bug of if I broke my installation by using SVN, so I didn't mantis it (sorry).

When I create a new page and hit "Save", I'm getting a Nullref exception in the logs:

The new page is saved okay and I wouldn't have noticed it if there wasn't an empty error message in the yellow error box on top. The error just says: "Error" and...

Is it my installation? Any ideas what I can do to fix it?

Hmm, something went wrong when Lucene tried to generate indexing information for this page. Not sure what could be causing this. The side-effect is that this page won't be in the index.

Pete is currently at LinuxWorld. So he might take a while to look into this.

I assume you already tried restarting dekihost, just in case?

Yup, restarted several times while narrowing down the cause of this bug.

BUT: Could it be that Roy fixed a part of it in r5063? The one he called "STUPID STUPID STUPID bug"... ;)
There's no empty error box anymore.

Hrmmm... I just checked, the exception is still in the logs. Okay, as long as it's just missing in the index, it's no real stopper for filling the wiki. I can reindex later when Pete will be back to look into it. Still I'm not sure if it's not a local thing, but maybe Pete will find out if it's a bug or not. In the meantime I'll try to find out something more about it and will recheck my installation the next days. I'll keep you updated how it goes.
