Debugger plugin crashes IDE in small window sizes

[deeptoaster]

If Geany Debugger is enabled (from the Plugin Manager) while the window width is less than 700px, Geany crashes.

Incidentally, if Geany Debugger is already enabled, I cannot resize the window to less than 700px wide, which prevents me from being able to use Geany on half my screen. It would be nice if this minimum width requirement could be removed as well.

Confirmed, but only when it's enabled after already being enabled and then disabled (the first time it just resizes the window to the minimum width). GDB traceback:

On a side note, I'm trying to compile the debugger plugin but it's giving me this error:

debug.c:53:21: fatal error: vte/vte.h: No such file or directory
 #include <vte/vte.h>

Is there something I'm missing?

#158 should fix this issue

Looks like you don't have libvte development files installed, but that's odd as the plugin should then be disabled… was the plugin disabled after configure bu you're still building it by explicitly running make inside its own subdirectory?
