I have reported this crash upstream.

Thanks

The threaded stack trace doesn't make much sense to me because it shows that bat is seg faulting in wait_data_intr() because the class pointer is NULL.

Can you answer the following?

- What version of the compiler are you using?

- Have you or the packaging changed any of Bacula's default compile options?

- Can you reproduce the problem? (off hand it looks like it)

- Can you show me how to reproduce it?

By the way, I use bat all the time via an ssh connection without problems.

Thanks,
Kern (upstream)

Hi Kern,

  thanks for your answer. I am using the default package provided by Ubuntu Hoary. I haven't compiled it nor have ich changed any compile options.

I think this error occurs, when i close bat via File->Quit but i am not sure if it causes same error as above.

I use bat 1.0 in combination with bacula director version 1.36 (Debian Sarge).

Regards,

Reinhard

OK.

Yes, we had several problems (seg faults, loops, ...) terminating everything
in Qt in the right order.

In your traceback, it appeared that you had just entered something into an
edit box when it failed. Perhaps you entered "quit".

I'm quite surprised that bat works at all with a Bacula Director version 1.36.

The first Director, with which bat works is 2.2.0 -- this is because we added
a lot of new console GUI support between version 2.0.x and 2.2.0. In fact,
bat can be successfully used only with the Director with which it was shipped
because we are still enhancing the console API.

To have a supported bat, you really need to move up to a 2.2.x version, which
may be a bit of a pain as there were at least 2 Bacula database upgrades in
between ...

Best regards,

Kern
