Good news, everyone. The bug is in fact located within pcmanfm (more precisely, within the GTK library part of, libfm-gtk1), and has been fixed by the author within the git repository of this project 9 days ago.
Since I have not read any further discussion about this bug any more and since I don't know the procedure in such cases, I simply attach a diff that fixed the bug on my computer. The patch needs to be applied against file "src/gtk/fm-dnd-dest.c" in the current source package of libfm-gtk1 of distribution Lubuntu 12.04. Whether the patch works against older versions of Lubuntu I don't know. Could anyone please try it or let me know the official procedure of providing patches? Perhapse the Lubuntu team is already aware about the bug being fixed and this whole commit is obsolete ... ;-) Best wishes, -- Stefan ** Patch added: "fm-dnd-dest.c.diff" https://bugs.launchpad.net/ubuntu/+source/file-roller/+bug/878993/+attachment/3190502/+files/fm-dnd-dest.c.diff -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to file-roller in Ubuntu. https://bugs.launchpad.net/bugs/878993 Title: x.org lockup after dragging archived file to desktop Status in PCManFM - File Manager: Unknown Status in “file-roller” package in Ubuntu: Incomplete Status in “pcmanfm” package in Ubuntu: Confirmed Bug description: 1 - Description: Ubuntu 11.10 Release: 11.10 2 - file-roller: Installed: 3.2.0-0ubuntu1 Candidate: 3.2.0-0ubuntu1 Version table: *** 3.2.0-0ubuntu1 0 500 http://us.archive.ubuntu.com/ubuntu/ oneiric/main i386 Packages 100 /var/lib/dpkg/status 3 - I was trying to extract a file with fileroller.
