[rdiff-backup-users] Failing backup: Long int too large to convert to int

[Thomas Jarosch]

Hello,

first of all, thank you for creating rdiff-backup, it's really
intuitive to use and has proven itself numerous times.

From time to time, rdiff-backup 1.2.7 crashes with the following message:

---------------------------------------------------------------------

OverflowError: long int too large to convert to int
---------------------------------------------------------------------

The box is running Centos 3 using python 2.2.3 and librsync 0.9.7+patch.

Any idea what could be wrong? Or some way to log the filenam
of the troublesome entry?

Thanks in advance,
Thomas
