[Evolution] Converting data after 1.5.7 installation

[Ludek Safar <lsafar suse cz>]

Hello,

I've decided the time has come for me to try 1.5.7 snapshot. I've
installed it with no problem, but after I gave it a try it reports a
message box with following text:

----
Insufficient disk space for upgrade.

Upgrading your data and settings will require upto 257519 KB of disk
space, but you only have 97183 KB available.

You will need to make more space available in your home directory before
you can continue.

Can someone share a thought with me where Evo gets a free space amount
information? There's almost 760 MB free on the partition where my home
resides...

Thanks a lot!

Ludek
