[PD] Bug: Unrecoverable iconified X window

[padawan12]

Not sure whether to report this because I'd classify it as priority 
low, just annoying.

Puredata 0.38.4 under XFree86/Fluxbox when minimising the "open" filebrowser
IFF all other windows are also minimised an attempt to deiconify the window
results in:

invalid command name ".x825fd60.m.windows"

No window can be reopned.

The server continues to respond to pd send comands from the shell
window but the pd-gui is doomed.

Anyone else?
