Details

On my up-to-date arch gnome desktop, when double-clicking an .EXE file, it opens in file-roller.
File-roller then says it could not find unzip. when closing the unzip-error-msgbox, and then closing the file-roller window, X crashes.

Steps to reproduce:
1. download an exe file from the internet (I can reproduce this bug using the latest putty.exe)
2. firefox will save it to the desktop
3. double-click the newly downloaded exe
4. file-roller (the "Archive Manager" titled window) will complain it couldn't find unzip
5. close file-roller
6. X crashes and you'll need to relogin in the GDM screen
This task depends upon

This is a bug in file-roller. When unzip couldn't execute, it sends a TERM signal to the pid that should have been unzip. The problem is that there's no such thing as an unzip process, and gnome-session receives the TERM signal instead. I guess this bug is present in older 2.24.x versions also.

BTW, why should exe files be assosiated with file-roller (and identified as zip archives)? the first bytes of EXE files are not similar to the first bytes of ZIP archives.
Comment by Jan de Groot (JGC) - Sunday, 30 November 2008, 19:32 GMT
Self-extracting ZIP files are executables too and file-roller can read those too. There's no easy way to distinguish between a normal EXE file and an SFX archive.
I'm building a patched file-roller that will only kill processes if their PID is not set to 0. When file-roller can't launch a process, the PID is set to the initial value of 0. Feeding this PID to kill, kill sends SIGTERM to every process in the same process group, which includes gnome-session and all your applications. When running file-roller from a terminal, the killing spree stops at your shell because it ignores SIGTERM.
