           Summary: some messages are blank after running out of disk
                    space
           Product: kmail2
           Version: 2.1.0
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: nisavid at gmail.com


Version:           2.1.0
OS:                Linux

this is with KDE 4.6.5 (not available in the dropdown).

i ran out of disk space today, which triggered about a dozen KDE bugs.  around
the time that i ran out of disk space, all of the following applications became
nearly or completely unresponsive: Konsole, Kopete, Kontact, and Amarok.  it
took me a while to realize what was happening (about 10-15 minutes passed
before i finally saw a "low disk space" notification), so i kept using some
applications.  one of the bugs i noticed is described herein.

before becoming totally unresponsive, Kontact was slightly sluggish but still
usable.  i viewed some messages in KMail, but some others showed up as blank. 
by "blank" i mean the following:

  * the message list shows the subject, the sender, the date, and all
associated status icons.

  * after clicking on the message, the preview pane shows the subject, the
sender, the sender's KAddressBook icon, the recipients, and the date.

  * the body of the message is empty, even if it actually isn't (as viewed in
another mail client).

  * "View --> View Source" produces a window with a single tab "Raw Source"
that contains a text area with two blank lines and nothing else.

the worst part is that after i cleared up some disk space, logged out, and
logged back in, the same messages still produce the same symptoms.  while this
bug certainly calls for a permanent solution, i would also very much appreciate
a workaround that would cause KMail to refresh the affected messages.

Reproducible: Didn't try

Steps to Reproduce:
1. run out of disk space.
2. view some messages.
3. clear some disk space.

Actual Results:  
* after running out of disk space, messages show up as blank, as described
above.
* after clearing disk space, the same messages still show up as blank, as
described above.

Expected Results:  
* after running out of disk space, messages show up normally, or an error
message is shown indicating that low disk space is causing a problem.
* after clearing disk space, messages show up normally.
