Bug 94541

Frank, thanks a lot for reporting, but I have a very hard time imagining that KMail could be causing these hangs. We've had no other reports of such behavior, and complete freezes like you describe are usually only caused by hardware failure, or powermanagement issue and such. I can't think of a way for KMail to cause a kernel oops, which must be what you see, since not even ssh login is possible. I'll close this bug report, as I don't see what we can do about it.

Till, thank you very much for your message. Normally I had also presumed that 
it is a hardware problem, but as it only occurs during mail composition with 
kmail, I thought it might be a problem within kde. I have still 3 month left 
of warranty of my notebook, so I should send it in ;-).

Thanks a lot and a happy new year
Frank

Does this happen while you are typing? Or while you are sending the message? Do you press a special key, e.g. the Menu key, when this happens? How often did this already happen (approximately)?

As Till already wrote an application running in user space shouldn't be able to freeze the whole system. I guess you already tried to switch to a text console (Ctrl+Alt+F1) or to kill X (Ctrl+Alt+Backspace) when your system was frozen. We had problems with KMail freezing X under certain circumstances, but never a system freeze.

Dear Ingo,

as you assumed, I've tried everything from console as well as from remote but 
the system was hanging. It happens during typing a new message and I think (I 
don't always look at the screen while I'm typing) it happens when I'm 
pressing the backspace key for 3 or 5 times in a short sequence. 
The frequency of this system freeze is about one to two times a week (at a 10 
hours daily system use).

Thank you very much again for your concern.

Best regards
Frank

P.S. I realize another phenomenon occurring during playing a wmv-file with 
mplayer. There also was a similar system-freeze for several times, but there 
the screen was jumbled up with different colors but mainly blue. It 
remembered me to a classical bluescreen under an insignificant operating 
system ;-). (This really was a shock to me, because these bluescreens have 
been one reason to totally ignore the existence of W...... 3 years ago).

Well, I don't thing KMail could do this. I write email very very often I use KMail every day and I tell you this cannot depend on KMail. I can immagine another thing and this is the solution. Your graphic card. This happened too me when I used the ATI driver for my ATI Radeon 9200 Mobility with DRI enabled. Now I'm using Xorg standard without DRI and they are OK because I don't need 3D aceleration. You told: "I realize another phenomenon occurring during playing a wmv-file with mplayer" then it's a graphic card problem. Try kernel 2.6.10 or just use Xorg driver because it's not a KDE problem surely, so I close this bug. If Till or Ingo think I'm in fault they can reopen it when they want.

Giovanni, 

thanks to you, too. A graphic-card driver problem is surely right with the 
anyhow only similar mplayer event and may be also right with the pretended 
Kmail problem. I'm asking myself why it occurs only during an email 
composition with Kmail.

But nevertheless many thanks for your help and hints.

Best regards
Frank

Hello.
Kmail still freezes my entire system during message writing. I can't access anything to stop it. No konsole, no ctrl+alt+esc, no nothing. It starts to freeze, when there are about 20-25 not correct words. Since I write messages in multiple languages (hungarian, english and russian), so freez comes I don't know why. I use Mepis linux 6.0 with kde 3.5.3. It is not a hardware problem. Thanks for dealing with this. why does a spellchecker freeze an entire system anyway?...

Hi, its me again. I turned off the auto spellcheck, but the mail composer still freezes my entire system, when typing in other languages. If you wanna see the problem, try typing something like this: "asklfghsdfj dfgdn dfgjdnh jdfgthf..." just letteres in no particular order, but after 5-10 letters a space, so kmail will think that these are separate words. Hope you will solve this.
