Recovery KMail after KDE crash

I uninstalled wrong library by mistake and dependencies took down half of my 
Debian system. I managed to recover after all (one step being reinstalling 
the kde package) without major loose of user data.

However I have problem with my old mails, archived in inbox folder:
When I open KMail, I see list of all the messages (subjects, sender, date...) 
properly. However clicking on any of the old (not received after recovery) 
mail turns it into "no subject, unknown sender and date" list item. Double 
click opens completely empty message. However there are messages with proper 
dates and sane lengths in ~/.kde/share/apps/kmail/mail/inbox/cur and I can 
open them by doubleclick in Konqueror, what opens perfect KMail message.

So I suspect some reindexing needed only, but did not find (googled) any 
usable how-to or FAQ on this point. Please help, any clue welcome.
