03dzyx - HTTP Error 500: Internal Server Error

Since March 5th , 2013 I've been experiencing issues with my private project

https://olemis@bitbucket.org/olemis/03dzyx

First I tried to pull changes and this is what I got

#!sh

$ hg pull bb_temp
http authorization required
realm: Bitbucket.org HTTP
user: olemis
password: 
pulling from https://olemis@bitbucket.org/olemis/03dzyx
searching for changes
abort: HTTP Error 500: Internal Server Error

I created a second fork hoping that this could be a local file system issue but this is what I got

#!sh

$ hg pull bb_temp
http authorization required
realm: Bitbucket.org HTTP
user: olemis
password: 
pulling from https://olemis@bitbucket.org/olemis/03dzyx_temp
searching for changes
abort: HTTP Error 500: Internal Server Error

Finally I thought this all could be about problematic changesets . Therefore I decided to strip some of them . First attempt @ b8fba9d and second one @ c02a3d8 both failed .

By looking at the repos history it seems that push is still working .

No hope I ended up with a useless repository and my team is frozen waiting for this to be fixed .

Q:

• Is it a known bug ?
• Is there any hope to get this sorted out soon ?
• Or shall we consider to abandon Bitbucket and look for something else ?
  If so how could we migrate the repository if we cannot read it ?

PS: I'm hoping my selection of ticket field values will accurately reflect the nature of this issue .
