Description Γιώργος Κυλάφας (Giorgos Kylafas) 2005-02-09 14:24:49 UTC 
Version:            (using KDE KDE 3.3.2)
Installed from:    Gentoo Packages
Compiler:          gcc (GCC) 3.3.5  (Gentoo Linux 3.3.5-r1, ssp-3.3.2-3, pie-8.7.7.1) 
OS:                Linux

When I try to attach a file over nfs, KMail crashes. KCrash tells me that KMail crashed and caused a SIGABRT signal, but due to Bug 71764, I have no backtrace for you, even if I have compiled KDE, Qt, X11 and glibc with debug information on (-g) and have not stripped the binaries.

Steps to reproduce:
1. Ctrl+N, for a new composer window
2. Add attachment -> Attach a file...
3. Put an address like this: nfs://server/path/to/file
4. Press button "Add attachment"

This happens with many types (txt, xls) and sizes (<150K) of files, using either port 716 or port 2049.

I also made the following attempts to get a proper backtrace, but all failed:

1. I run KMail from gdb, but gdb exited with the error:
(gdb) run
Starting program: /usr/kde/3.3/bin/kmail
[Thread debugging using libthread_db enabled]
[New Thread -1249226112 (LWP 18929)]
ERROR: Communication problem with kmail, it probably crashed.
Program exited with code 0377.

2. I attached gdb just after running KMail, but gdb would not continue after a point and would produce a message like this:
(gdb) c
Continuing.

Program received signal SIG41, Real-time event 41.
0xffffe410 in ?? ()
(gdb)

3. I attached gdb just before pushing button "Add attachment" (step 4) and I got the same message as above.

4. I attached gdb after the crash, and all I got was:
(gdb) attach 18940
Attaching to program: /usr/kde/3.3/bin/kmail, process 18940

I upgraded to gdb-6.2.1 (from 6.0) and managed to get the following backtrace:

Ingo recently fixed that assert.
