d.mon errors when closing

[veroandreo]

When I close the wx monitor after displaying a raster and trying to display a raster legend, or only after displaying a raster or vector map, I get:

wx._core.wxAssertionError: C++ assertion "GetEventHandler() == this" failed at ../src/common/wincmn.cpp(477) in ~wxWindowBase(): any pushed event handlers must have been removed

The above exception was the direct cause of the following exception:

Traceback (most recent call last):

Should be fixed in master. Please test, needs backport.

Yes, GH 383650806c3505fb677cc2d5474cd1325ac17cc9 solved it.

Still I see this bug when entering a wrong map name (just happened when testing, here I just a fun name):

During handling of the above exception, another exception occurred:

I have backported GH 383650806c3505fb677cc2d5474cd1325ac17cc9

[veroandreo]

d.mon error at closing is gone, but I get the same error reported by Markus if the map does not exist.

[annakrat]

Fix is in master now.

[neteler]

Replying to annakrat:

Fix is in master now.

Your fixes solve the remaining issue. I have backported it, works fine now in 7.8 (so it is for 7.8.1 then).

Thanks! & closing.
