Hm that error maybe have something to do with orphanes.
pictureshack.ru is inaccessible atm but peering at the image reveals a boost exception with the unedifying message: The attempted operation is not supported for the type of object referenced.
At least there *is* an error message, it's a starting point.
* gjhiggins wanders off to investigate whether wine can still install Qt, one never knows.
