sounds like there is still air in the system, its getting hot and popping the seals when the trapped air finally wants out.

my guess as to the problem:
when u are bleeding the clutch, the first few times you have to MANUALLY push the clutch fork all the way back in under the car (to get the slave pin completely back inside the slave) with bleeder valve open (this can be a bit difficult). close bleeder valve while keeping the fork held in above position, build the pressure back up, and repeat. if you are not doing this the air is trapped in the slave, but it seems like its bled.
the other thing it could be is air getting into the system thru a loose connection or a leaking master cylinder. if the master cylinder is leaking, you'll most likely see fluid INSIDE the car on the firewall where the master connects to the pedal.

hope this helps

edit: also how is the clutch engagement point? the clutch pedal itself may need adjustment if the clutch isnt fully disengaging. this could also cause the fluid to overheat even if it is properly bled. easiesty way to check this is to jack up the diff to get the rear wheels of the ground and start the car in neutral. if the wheels turn the clutch is not fully disengaging
