i just installed Pylon5.2, and i got:
* the gem_videoPYLON.so plugin (compiled against 5.0.12) doesn't load at
all (because Basler correctly changed the name of the dynamic libraries,
becaus they probably introduced incompatibilities)
** the important part here is, that i don't get any crash with old
plugin and new Pylon
* compiling videoPYLON against Pylon5.2 worked nicely
* i can open the Pylon dummy device (PYLON_CAMEMU=2) nicely with Pylon5.2
** the important part here is, that i don't get any crash with new
plugin and new Pylon

so from my perspective, there does't seem to a be a problem :-(
otoh, i could only test with a dummy devices, and not with a real device
(you probably need to update some firmwares on your devices...)
