Package: libkio5
Version: 4:4.11.3-2
Severity: important

Dear Maintainer,

If i use the libreoffice-kde integration package, the opening of a file dialog
rises a SIGSEGV.

If i try to attach to the process with gdb or valgrind the problem disapear.

However, i can get a coredump that gives :

Core was generated by `/usr/lib/libreoffice/program/soffice.bin --splash-
pipe=5'.
Program terminated with signal 11, Segmentation fault.
#0  checkValidity (current=..., this=0x540058) at
.../../kio/kio/delegateanimationhandler_p.h:46

[...]

I also tried to change the line 1291 of kio/kio/kfileitemdelegate.cpp with

            fprintf(stderr, "cache = %p\n", cache);
            fprintf(stderr, "  valid = %d\n", cache->valid);
            if (cache->checkValidity(opt.state) && cache->regular.size() ==
opt.rect.size())

When i run libreoffice and open filechooser dialog i get :

cache = 0x3a37b80
  valid = 1
cache = 0x3a37b80
  valid = 1
cache = 0x540058
SIGSEGV

So cache pointer seems to be corrupted.
