[X2Go-Commits] [x2goserver] 01/01: Safely remove desktop files for client-side shared folders. Remove the correct desktop file, even if the shared folder has already been (forcefully) umounted. Such situations occur in cases where the connection gets interrupted. SSHFS will then get removed by the Linux kernel and we have to "guess" what desktop icons is actually to be removed.

Safely remove desktop files for client-side shared folders. Remove the correct desktop file, even if the shared folder has already been (forcefully) umounted. Such situations occur in cases where the connection gets interrupted. SSHFS will then get removed by the Linux kernel and we have to "guess" what desktop icons is actually to be removed.
