[120315 15:28:12] Database has been successfully dumped to SQL file(s)


Description of my issue:

- I have defined a new profile for only backing up the databases, the main one of the joomla installation and another one, not a joomla-db.
- Testing connection to the non-joomla-db works correctly
- In the Configuration, Backup Type is set to All configured databases (archive file)

After starting a backup and finished "successfully" (as noticed by akeeba backup pro), the archive is created and there are several files belonging to the joomla database and one more 91ADBBC3-db316104222.sql (see log file above) that should contain the mysql dump of the other database (or not?) but this file has 0 bytes length.

As you can see in the logs above, something goes wrong there (many notices - maybe not important - and a PHP warning)

What could be the issue or problem?
Do you need extra information?

Here is the Log file (ZIP)

Yes, you are right, there was a problem showing the tables with SHOW TABLES! Very strange, but that was the problem.

Thank you very much!

Maybe, you could or will catch such a case showing a message to the user in a future update o Akeeba Backup if you find that could be useful.

PS. You have made a great documentation! Real good work!

I understand and I had to ask google what this "Catch-22" is :-)
Thank you again. I think, you can close this ticket.
