Fixing src:uglifyjs

[Santiago Vila <sanvila@debian.org>]

Hello.

I'm trying to keep stable free of FTBFS bugs, and there is one package
which slipped to the current stable release before anybody could fix it.

In this case there seems to be some kind of problem with version tracking,
and, as a result, the bug was filed three times:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1072609
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1091037
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1101597

I wonder if anybody here would help me to fix this bug, either
directly, or by telling me how to proceed.

After that, I'd like to prepare an upload for proposed-updates and
take care of related bureaucracy.

Thanks.
