| Bug 106390: knode crashes when trying to retrieve Articles from a specific Server | (crash) |
| Opened: | 2005-05-27 20:24 |
| Product: | knode |
| Component: | general |
| Version: | unspecified |
| Status: | RESOLVED |
| Platform: | FreeBSD Ports |
| Resolution: | FIXED |
| Reporter: | Ralf Folkerts |
| Assigned to: | KNode Developers |
Version: kdepim-3.4.0 (using KDE KDE 3.4.0)
Installed from: FreeBSD Ports
Compiler: gcc (GCC) 3.4.2 [FreeBSD] 20040728 CPUTYPE=athlon-xp, CFLAGS= -O -pipe, no CXXFLAGS
OS: FreeBSD
On my System, knode normally works fine (I'm running a local leafnode-Server; knode never ran into troubles with it); however, whenever I access a certain News-Server knode crashes. I thought that Server might be corrupt (and it may be). To just I installed Thunderbird; this doesn't run into any Problems with that Server (which does not prove, the Server is not bogus, of course!).
That server is "news.ecomstation.com". I can download a List of Groups w/o any Problems; however, when I subscribed to a Group (I tried the "ecomstation.advocacy") and want to download the Articles knode's Progress-Bar proceeds to 10% very fast and then sticks there. After a while knode crashes.
As by suggestion from FreeBSD-KDEs Michael Nottebrock I compiled the KDEPIM-Package with "WANT_KDE_DEBUG" defined. After that the console displays:
knode: KNApplication::newInstance()
knode: KNArticleWidget::showBlankPage()
knode: KNGroup::readInfo(const QString &confPath) : using alternative user for Interne News

knode: Fatal IO error: client killed
Unfortunately I don't have a Backtrace; the CrashManager displays that knode was killed by a Signal 11 (SIGSEGV). The "Backtrace" Window shows:
"Eine korrekte Rückverfolgung ist nicht möglich.
Wahrscheinlich sind die Dateien Ihres Systems in einer Weise erstellt worden, die eine solche Rückverfolgung (Backtrace) nicht erlaubt. Oder der so genannte "Stack Frame" für das Programm wurde durch den Absturz unbrauchbar gemacht."
I hope the error is reproducible; if not and you need more information pls. let me know! Thanks!
