Description:
there seems to be some regression in scim. i installed it couple months ago, used it occasionaly when needed to type in russian or chinese, only today i noticed some strange behaviour. The only place it would sorta work at is the terminal window i open straight on boot with xinitrc to load a simple text file with nano. Default trigger Control+space would not let me change normally between the input methods in any other places, neither does the left-click on tray-icon submenu. it will be clickable, but it wouldn't seem to change, nor it would load that special toolbar for secondary language. Now that's if i start it from xinitrc and put export XMODIFIERS=@im=SCIM export GTK_IM_MODULE="scim" export QT_IM_MODULE="scim" lines to xinitrc, just how i did id for all this time.
if i remove scim -d from xinitrc as well as those export ... lines, and just load, say, seamonkey from the terminal by GTK_IM_MODULE="scim" seamonkey it all functions as expected on every application boot.
Also, to test it even further, it all functions just fine if you start ibus from xinitrc with all those export ... lines. So it's pretty messy. I'll try to record some gifs in following messages maybe to make it more understandable

Additional info:
* package version(s)
scim 1.4.17-1, scim-tables 0.5.14.1-2, scim-pinyin 0.5.92-3
* config and/or log files etc.
doesn't really seem to cause any errors, or maybe i just don't know where to find them. Anyway two logs for the starters:

Steps to reproduce:
1. pacman -S scim scim-pinyin scim-tables
2. add smart pinyin and russian computer in scim-setup, log out
3. edit xinitrc to have something like this
export XMODIFIERS=@im=SCIM
export GTK_IM_MODULE="scim"
export QT_IM_MODULE="scim"
sleep 1 && scim -d &
4. log back in

added three little screencasts showcasing the original problem.
   scim-xinitrc (153.2 KiB)
   scim-by-had (667 KiB)
   ibus-xinitrc (175.7 KiB)

so i guess the best way to summarize it would be: scim does not do a very good job getting those variables for GTK_IM_MODULE, QT_IM_MODULE, XMODIFIERS being exported (not for a single user thru xinitrc, nor system-wide thru /etc/profile) anymore (whatever caused the regression, cuz frankly speaking scim-related packages have not been updated in a while), but it still functions as expected if it is explicitly told to by launcihing the application with that GTK_IM_MODULE="scim" or QT_IM_MODULE="scim" prefix

i was able to reproduce it on a fresh install. attached is the pretty much complete log of my post-install procedure with the two marks of having scim working at the very early stage, and not having it working few very simple steps later
PS reported upstream as well https://github.com/scim-im/scim/issues/19

thanks for being patient!
turns out i noticed the "regression" after installing tint2. before i was using plain openbox. spending a little time testing, including the fresh install, reveals that loading scim daemon before the panel (sleep 1 && scim -d / sleep 2 && lxpanel &) solves the problem. will double-post that upstream. if no one objects i could also add info on that "work-around" to the related scim wiki page.
cheers!
