Bug#571962: azureus: Fails to start with "Azureus core already instantiated"

[Ross Vandegrift]

Package: azureus
Version: 4.3.0.6-1
Severity: normal

I recently upgraded to 4.3.0.6-1 from 4.3.0.0-1 on testing, and azureus
now fails to start every time with the same Java traceback.  I have
downloaded the official 4.3.0.6 and it does not exhibit this issue.  I
have confirmed that there is no copy of the software running, no
existing JVM, and have even logged out and rebooted.  Both the Debian
package and the official release are using the same JVM.

Traceback is below.  I can reproduce 100% of the time and am happy to
provide any additional information.

Thanks,
Ross
