Then I opened KMail standalone and apparently it was working this time, I marked a few mails as read, changed folder and... it blocked (not crashed, blocked). Right now KMail is unusable for me. I forgot to report that I have 3 Gmail IMAP, 1 POP3 and 1 local mailbox accounts configured.

Can you open the system monitor before starting KMail and check the memory consumption of it after its start? If it tries to grab all available memory and finally crashes, you're probably facing the consequences of a filter bug of the old version described in bug 289277. You might have now mails in your folders each with 100MB and more and KMail simply runs out of resources now.
