Description Aaron Williams 2020-01-15 12:06:36 UTC 
Application: kmail (5.13.1 (19.12.1))

Qt Version: 5.14.0
Frameworks Version: 5.66.0
Operating System: Linux 4.12.14-lp151.28.36-default x86_64
Distribution: "openSUSE Leap 15.1"

-- Information about the crash:
Every time I type in an email address into KMail to send or reply to an email it crashes when it attempts to autocomplete the address. I have tried deleting all of the entries in the composer settings yet it still crashes. If I type the complete email address elsewhere and copy and paste it then it works fine. I cannot figure out where KMail stores these email addresses (I performed a grep on .local/share and .cache and found nothing). It does this on two separate computers (which have access to the same emails).

The crash can be reproduced every time.

-- Backtrace:
Application: KMail (kmail), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".

Comment 1 Aaron Williams 2020-01-15 12:18:40 UTC 
Note that I deleted all of the recent entries in the composer settings page and it still crashes. I do not know where this database is stored for completion. I grepped for a name under .local/share/ and under .cache and /tmp and /var/tmp but I could not find the database. Note that I also have seen this same crash on another computer. It started up in the past few months. I also have a LOT of emails, going back over two decades.

Try to delete ~/.local/share/akonadi/searchdb/, or if that doesn't exist all subfolders in ~/.local/share/baloo/ except "file" (which contains the file index).

> Try to delete ~/.local/share/akonadi/searchdb/

Sorry, typo.
The folder is named search_db (with a _ ).
Comment 4 Aaron Williams 2020-01-25 23:27:19 UTC 
I deleted the search_db folder and that appears to have solved it. My guess is something in it caused the internal data structures used by KMail to become corrupted and crash. I was at my wit's end with this and resorted to copy/pasting email addresses. Hopefully, this doesn't return.
Comment 5 Justin Zobel 2022-10-03 10:36:21 UTC
