Getting "HTTP Error 500: Internal Server Error" on hg push

Hi,

When I push my changes to my bitbucket repository, I get this error:

hg push --new-branch

pushing to https://GFX47@bitbucket.org/GFX47/gladiabots\\
http authorization required for https://bitbucket.org/GFX47/gladiabots\\
realm: Bitbucket.org HTTP
user: GFX47
password:
searching for changes
abandoná: HTTP Error 500: Internal Server Error

I have 30 outgoing changes, I thought maybe it was caused by the amount of data to push so I tried to only push one revision (-r XXXX) but I get the same error.

Thanks for your help.
