Comment 4 for bug 822479

Some addition to the bug scenario:
I've fresh installed ubuntu 11.04 on a new laptop, then I backed up all my evolution data from the old laptop and imported the backup onto the new one. After that operation evolution on the new laptop started to eat up ram in horrible way, taking around 100MB of memory for each message opened, and never freeing memory.
So I've cleaned the configuration files of evolution and the locally downloaded mails. After this step evolution seems to does not eat up memory by simply opening messages.
Before the operation it was leaking about 100MB of memory for each message opened.
The removed files to clean up config and downloaded messages are
~/.evolution
~/.local/share/evolution
~/.config/evolution

The memory leak could be related to the big quantity of locally stored messages (around 2Gb), or with a setting coming from the old setup that triggered a bug in evolution.
Is there a way to test whatever setting caused the issue?
