[Kolab-devel] [issue1222] Crash on signing large attachments

[Torsten Irländer]

New submission from Torsten Irländer <torsten.irlaender at intevation.de>:

Revision  526323                
                
Kontact sometimes crashes while signing large attachments (~18MB). This error                
can be reproduced but the way how to to this is a little bit ...  curious.                
The crash only seems to happen on direct send. If you put the Mail into the               
"Posteingang" first all works fine for me here.               
               
To reproduce this error you will need to create some emails with large               
attachments and sign them. A Dialog asking for your passphrase will pop up               
after clicking on the send button. For me the composing windows stays focused               
here and so it often happens that I type in my passphrase and nothing happens.               
This seems to be important as the crash almost alway happens after I typed my               
passphrase into the "nomansland" the first time. After you enters your               
passphrase in the dialog correctly Kontact begins to sign the message and tries               
to send it.              
             
Now there might be three situations:            
            
1. Mail is sent. Fine!            
            
2. The sending is interrupted by an error message saying the the sending is            
interrupted  by an unknown error. The error message informs me about the used            
profile and suggests some possible errors. After that the mail is still in the            
Postausgang.            
            
3. Kontact crash. Its last words on the konsole are:            
                   
kmail: normalizedAddressList: "Torsten Testländer <torsten at test.hq>"          
*** KMail got signal 6 (Crashing)          
KCrash: Application 'kontact' crashing...          
kio (KIOConnection): ERROR: Header read failed, errno=104          
kio (KIOConnection): ERROR: Header has invalid size (-1)          
kio_imap: IMAP4::slave_statu          
  
After the crash the mail can be found in Posteingang. Sometimes there is an  
additional Ghostmessage (completely empty mail) too.   
        
Sorry, but I can not provide you with any additional info on this crash as no        
crashmanger gets started to make some backtrace. even gdb gives me         
no more information. I tried to do valgrind, but this is not easy as this error     
happens  only sometime.     
Will try to provide more info, but for now I want to go sure that this bug    
won't be forgetten.
