Description Giovanni 2019-10-14 06:51:18 UTC

Description of problem:

I'm using the "surf" browser (provded by the "surf" package in Fedora 29).  Surf relies on dmenu for user input (e.g. when opening a new page), but dmenu crashes.

After a little debugging, I found out the cause to be 

Version-Release number of selected component (if applicable):


How reproducible:

Easy to reproduce



Steps to Reproduce:
1. LANG=C.utf8 dmenu
2. insert some text, e.g. "about:blank" (which is what surf does)
3. When the graphical input text bar is shown, type some words and it should crash.

Stack trace of thread 10673:
#0  0x00007fc3a208c514 XmbLookupString (libX11.so.6)
#1  0x00005613aab5a3a3 keypress (dmenu.real)
#2  0x00007fc3a1e31413 __libc_start_main (libc.so.6)
#3  0x00005613aab5b34e _start (dmenu.real)

The crash does not happen with LANG=en_US.utf8 (which is what I have if I run dmenu myself, while surf is probably changing the values of the environment variables.
