Yes, Valentina is optimized for max performance at run time, so there 
is some crashing when starting to develop. You can set the debugging 
level before calling init (I think it is the first or second function 
described in the vxcmd manual). This function allows you to turn on 
additional error checking in kernel during development (at the 
expense of performance), although it won't necessarily stop crashing 
if things are called out of order. The errors are passed back as the 
result in format "error nnn" but a few functions return true/false so 
watch out.
