Please describe the problem:
When listing folders of an IMAP account, Evolution incorrectly recodes the names
to some weird encoding. I am unable to access most of my mail (gets
automatically sorted into folders with diacritic symbols) - the folder list on
the left shows garbage and trying to access a folder results in an IMAP error
saying that such folder does not exist.

This is a regression - was working ok in 2.4.1, stopped working after I upgraded
to 2.4.2.1.

Steps to reproduce:
1. Create an IMAP folder with name containing accented characters
2. Launch Evolution
3. Try to access the folder

Actual results:
Get folder info(0x81ac0b0:imap://patrys@mail.icenter.pl/, '<null>') =

Notice it sends something different from what it received earlier.

Expected results:
Should work as it did before the upgrade ;]

Does this happen every time?
Every time.

Other information:
As mentioned above - this is a regression that bugs me since I upgraded from
2.4.1 to 2.4.2.1

Using PLD Linux Ac i686, latest packages from

I am also a PLD Linux developer so I can tell you that our build system did not
change between these two versions.
