Created attachment 18136 [details] Output of strace when running gpk-update-viewer Hello, When Packagekit doesn't work on my system, I searched for the reason and found it: PackageKit doesn't work when libtrash is installed (and running) an a system. Libtrash is an popular application, preventing the user form deleting files irreversible. It ca be found here: http://pages.stern.nyu.edu/~marriaga/software/libtrash/ For getting libtrash work, you need to add the following line to the .bashrc-file: export LD_PRELOAD=/usr/local/lib/libtrash.so But having this line in your .bashrc will inhibit Packagekit from running. Libtrash has also an option to disable libtrash temporarily, doing "export TRASH_OFF=YES". This works fine for other applications having problems with libtrash - but it doesn't change anything with Packagekit. The only possibility, to get Packagekit working it to remove upon line form .bashrc and restart the X-Server (or log-out & -in completely new?). When libtrash is enabled and I'm running Packagekit, I'm getting a segmentation fault. The strace an ltrace are attached.

Cause Libtrash is very popular and very, very usefull when working on the bash, I hope you can fix this bug in near future. My System: Fedora 9 libtrash 3.0 packagekit 2.3-6 installed by yum gnome-packagekit 0.2.3-9. installed by yum Best regards, Michael Schönitzer
Does it stop packagekitd or gpk-update-viewer from running? If it's the latter, can you grab a backtrace using gdb after installing the needed debuginfo's. Thanks.

It stops all gpk-*-applications. I've installed all the debuginfos: $ debuginfo-install GConf2.i386 ORBit2.i386 PackageKit.i386 PolicyKit-gnome.i386 PolicyKit.i386 atk.i386 cairo.i386 dbus-glib.i386 dbus.i386 expat.i386 fontconfig.i386 freetype-freeworld.i386 glib2.i386 glibc.i686 gtk2.i386 libX11.i386 libXau.i386 libXcomposite.i386 libXcursor.i386 libXdmcp.i386 libXext.i386 libXfixes.i386 libXi.i386 libXinerama.i386 libXrandr.i386 libXrender.i386 libcap.i386 libglade2.i386 libnotify.i386 libpng.i386 libselinux.i386 libxcb.i386 libxml2.i386 pango.i386 pixman.i386 sqlite.i386 unique.i386 zlib.i386 gtk2.i386 Then I did: $ gdb gpk-update-viewer GNU gdb Fedora (6.8-12.fc9) Copyright (C) 2008 Free Software Foundation, Inc.

Okay, this is showing that gpk-application is segfaulting as soon as it calls into the libpackagekit library. There's something wrong with libtrash I think, as I can reproduce using: export LD_PRELOAD="/home/hughsie/Code/libtrash-3.2/src/libtrash.so.3.2" gpk-appication --verbose (gdb) bt #0 0x00000000 in ??

I don't know how to debug this, sorry.
Okay, I've been playing with ld during lunch and it seems that libtrash can be used if libpackagekit is compiled with -export-dynamic. I've made this change in master and 0.2.x -- so this will be fixed when I release 0.2.5 which should be in about three weeks time. Not using -export-dynamic also exposes a bug in gnome-packagekit, which I've also fixed.
