[kdepim-users] Gentoo kmail2 experience

[Peter Humphrey]

Hello list,

Last Sunday I bit the bullet and allowed kmail to be upgraded to 4.10.4, which 
is the same version as KDE. This is what happened:

1.	Moved /home/prh to /home/prh.old, created new /home/prh and copied 
essential stuff from old to new (.bashrc, .mozilla etc.).

2.	Removed /etc/portage/package.mask, which had been preventing the upgrade 
until then.

3.	Logged in as prh, ran kmail and told it to import messages from 
../prh.old/.kde4/share/apps/kmail/mail.

4.	Moved the imported folders to directly under Local Folders.

5.	Told kmail to import my filters from 
../prh.old/.kde4/share/config/kmailrc[1].

6.	Logged out and in again to make sure of a clean slate.

7.	Fetched mail from my one POP3 account (I haven't created any IMAP 
accounts yet).

8.	Found nearly every message duplicated. Ran Folder | Remove Duplicates in 
each affected directory. That almost worked, but (a) it took a long time to 
clean the whole of GentooUser, which has about 8000 messages in it and 
growing, and (b) once or twice it removed the wrong one of a pair, leaving a 
message dangling outside the thread it was supposed to be in.

So far I've had one message not duplicated, and a few duplicated twice - i.e. 
there were three copies.

I've only tried searching once and got a silly error about permissions. More 
testing to do here. By me, I mean.

Can I do anything to prevent (nearly) everything being duplicated?

If I get fed up with the duplication and want to revert to kmail1, will it be 
able to import from the kmail2 structure?

[1]	The filter import process is untidy. There's no way to abort part-way, and 
it isn't clear what will happen if I click Cancel when an incoming filter 
refers to a nonexistent folder (I did still have a number of old, redundant 
filters which ought to have been cleared out before). In fact it leaves an 
incomplete filter, which I have to go through and delete by hand. Better would 
be to allow discarding of the filter. In short, importing filters requires 
previous experience and manual tidying.

Peter
