* doing shift-pagedown then shift-pageup should do nothing (increase then decrease the selected_files)
* after a delete, the focus is not given back to sfm
* on a directory symlink, ls -ld <the-link> says it is directory as the action
is called with a '/' following the directory symlink
* sometimes, there are actions that are leaved alone as ``zombies''
* problem with cdm when the directory contains spaces (eg: "/tmp/the dir/")
* no protection when doing a long action (eg: you can enter a directory you are 
deleting or moving). Can cause a sigsegv.
* using views on different pages of a virtual desktop (virtual window managers)
causes an error from the X server (like BadMatch).
* (seems to be fixed) sometimes, you get "Xlib: unexpected async reply (sequence
0x3724)!". I don't know why. I thougth it was using signal(2) to handle the
signals I use, and to use gtk functions in this handlers. That's why I replaced
these handlers by a gtk_signal_emit to the real handler. It seems better. It
also seems not enough... As it's hard to make it bug, I'll wait until I can
make it bug repeatedly.
* you can't scroll horizontally so you can't see the whole file names
(workaround: enlarge sfm or rename the file)
