           Summary: konsole crashes at startup probably getting out of
                    memory
           Product: konsole
           Version: unspecified
          Platform: Fedora RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: konsole-devel kde org
        ReportedBy: teke math su se


Version:            (using KDE 4.0.3)
Installed from:    Fedora RPMs
OS:                Linux

After starting konsole its memory use grows to about 200 Mb and then crashes.

Running under gdb shows that it crashes at
0x07ac9cdc in _int_malloc (av=<value optimized out>, bytes=<value optimized
out>) at malloc.c:4085

Giving a backtrace is not possible as there seems to be some (almost) infinite
recursion happening. 

Going up a few steps gives this:

#1  0x07acadc6 in malloc_check (sz=<value optimized out>, caller=Could not find
the frame base for "mallo
c_check".
) at hooks.c:265
265       victim = (top_check() >= 0) ? _int_malloc(&main_arena, sz+1) : NULL;
(gdb) 
#2  0x07acbbf5 in __libc_malloc (bytes=<value optimized out>) at malloc.c:3546
3546        return (*hook)(bytes, RETURN_ADDRESS (0));
(gdb) 
#3  0x005bbd9d in qMalloc (size=Could not find the frame base for

(gdb)

(gdb) up 10

Further attempts to go up leads to the same position:

    shortPath=<value optimized out>)
