exceptions.OverflowError: long int too large to convert

[Lars Vierbergen]

The error bzr: ERROR: exceptions.OverflowError: long int too large to convert occured when I was trying to open a branch from a virtual repository. It is branched from another local branch and has a lot of file changes that are not yet commited.
Running bzr 2.3.4 on python 2.6.6 on windows 7

[Lars Vierbergen (vierbergenlars)]

This is not an issue on ubuntu 11.04. Maybe it is important to say that my windows is 64 bit (bzr is running 32 bit virtualisation)

[Martin Packman (gz)]

This can be worked around if you find the problem file, which will either be >4GB in size, or have a timestamp in the far past or future.
