           Summary: KMail search gets confused with temporary files
                    (choking on swallowed characters in filenames)
           Product: kmail
           Version: 1.13.5
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: NOR
         Component: search
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: kde-bugger at msquadrat.de


Version:           1.13.5 (using Devel) 
OS:                Linux

While trying to debug bug 211885, I stumbled upon a weird behaviour of KMail,
as described in comment #65 over there:

----8<----
[...] I see another weird thing, KMail is renaming/removing the
search folders randomly.  I actually saw it first in comment #63:  I created a
Search Folder named test and exited.  After I restarted Kmail, I had two Search
Folders: test and Test.  Well, I didn't have enough coffee yet, so I discarded
it as a personal brainfuck.  I removed both the folders.

Now I tested it again and kept the Last Search folder name, restarted KMail,
and I suddenly had my old folder called test again.  With the old search
settings.  WTF?

So I removed test again, did another search called Last Search, shut down KMail
and had a look at the ~/.kde/share/apps/kmail/search directory:

mss at Otherland:~/.kde/share/apps/kmail/search$ cat Last\ Search 
[Search Folder]
Base=.1081015519.directory/INBOX
Recursive=true
contentsA=testest
fieldA=<message>
funcA=contains
name=<unknown>
operator=and
rules=1

So far so good.  Now I restarted KMail and had no Search Folder at all!  The
file Last Search was removed from the harddisk as well.

Something is very odd around here.  But KMail doesn't crash.

It seems like KMail got confused internally about its searches.  Next is the
debug output etc. of KMail starting with an existing search folder Last Search
("Can not find parent folder for  Last Search"), once it runs I created a new
search called test.  Note that KMail swallows the last character of the old
search folder name (".Last Searc.index.sorted").
