no keys with modifiers accepted anymore

[pmarek]

I've had it now 3 times that no keys with modifiers are accepted anymore; ie. I can enter "abc", but no character like "!" (shift+1), "«" (AltGr+x), etc. These are simply not taken (xchat text input line).

I've now had that while running xpra with "-d all"; here's the (hopefully) relevant part of the log. I hope that this client log is enough.

I've marked a few lines with "==========" to explain the approximate state; perhaps having a timestamp every so often would be a good idea, too.

Here's something I found in the xpra server log, perhaps that helps, too.

The client log looks ok, I am much more interested in the server log...

The error in comment:1 has been fixed already, see r433 - that may well solve your problems

[pmarek]

I've found multiple instances of these messages, too ... but that's all there is in the server log.

bug in comment:4 is fixed in r444 - as far as I can tell, this should only happen when old clients connect?

[Antoine Martin]

silly bug fixed in r445, to test that this fixes it, also apply this:

             return

To make the keys_changed fire everytime the session statistics tray menu is clicked, this used to break the keymap and no longer does.

I assume this is fixed, please re-open if necessary.
