Bleah. I just checked on my primary system (where I never use env LANG=C, just leave it at the default (empty) value for that system), and the bug is NOT tripped there. That system uses FVWM as my desktop, not gnome. The issue is repeatable and consistent on Ubuntu with gnome fallback, though. Have not noticed any scrambling of config files with the default system LANG (en_US.UTF-8) on the laptop. I just looked in xa_config.c and it appears that that is already overriding LC_NUMERIC and LC_CTYPE to "C" to avoid exactly the problem you describe. (I was going to suggest that maybe it should do that, and checked first only to find it does). So perhaps setting LANG is no longer helpful? In my case (on the laptop I use for SAR) it is definitely harmful. > On Wed, Mar 25, 2015 at 4:21 PM, Tom Russo <[email protected]> wrote: > > On Wed, Dec 31, 2014 at 11:47:06PM -0700, we recorded a bogon-computron > > collision of the <[email protected]> flavor, containing: > >> Have had this issue a few times recently while trying to use Xastir on > >> Ubuntu 14.04 during SAR missions. > >> > >> After a few uses of dialog boxes, suddenly am finding that I can't type > >> into > >> the text fields.
