[Users] Need clue stick for crash on entering Inbox

Mon Jun 9 20:40:17 CEST 2014

Hi guys!

Couple of days trying to track this down is driving me nuts...  could use
a clue stick, even if it comes in the form of a 2x4...  :)

Got a new laptop[1].  Compiled CM on it and copied over all files from
the two instances I run.  Long story short: I thought there was a problem
with the copy until I restarted CM on my old machine...  same crash when
I click on Inbox...   The really strange part: in one test, I clicked on
all the other folders first (starting from the bottom), when I got to
Inbox, there was no crash.

Suspecting that some message came in and set things up to fail; but no
idea what and when...

--debug and gdb have not been very helpful so far.

Copied 400+ msgs (dating back 6+ months) to a test account, and no crash.

The details...

######### --debug
Wait until CM finishes starting and click on Inbox gives:

######### gdb...

Start CM, attach gdb and wait for gdb output to stop, then:
(gdb) step
Single stepping until exit from function poll,
which has no line number information.

## here, waiting for activity...  so I click on Inbox.
## The next gdb output is simply this:

## Use of 'stepi' can go on and on forever in various libs; but gives no help because I never reach the failure...

I can provide bt full output if that will help...  However, 'str1' looks
interesting here:
#2  0x00000000005baa7a in summary_cmp_by_from (clist=0x17cb610, ptr1=0x2a35500, ptr2=0x2972620) at summaryview.c:7452
        str1 = 0x75f8e0ba85d1a794 <Address 0x75f8e0ba85d1a794 out of bounds>
        str2 = 0x29765d0 "support at placester.com"
        r1 = 0x2a35500
        r2 = 0x2972620
        msginfo1 = 0x1e2a650
        msginfo2 = 0x1e005d0
        sv = 0x1a46730
        res = 32767

summaryview.c:7452
	res = g_utf8_collate(str1, str2);
main.c:1559
	gtk_main();

I have several messages from this sender; but I'm not sure which one
might be triggering this crash...  strangely, copying entire Mail (9.3G)
to new machine gives same crash; but copying last 6 months messages into
my test CM doesn't...

In case it matters, CM dumps this at startup:
** (claws-mail:1731): WARNING **: Trying to register gtype 'GtkCMUnit' as
enum when in fact it is of type 'gint'

Thanks,
Pierre

[1] i7 does NOT mean an 8 thread CPU!  The only way to be sure is check
the CPU specs.  Returning Dell Inspiron 17R 5737 i7 which has only 4
threads. :P
