Interesting little Segfault w/r to signal/slot connection

Is that the only Qt4 version you have on your system?

datagen.cpp:34: error: invalid conversion from `unsigned int' to `QTableWidget*

I forgot to add casts:

DataGen::DataGen() : m_munPhRanges( (QTableWidget*)0xdeadbeef ), m_munPkRanges( (QTableWidget*)0xcafebabe )

DataGen::DataGen() : m_munPhRanges( (QTableWidget*)0xdeadbeef ), m_munPkRanges( (QTableWidget*)0xcafebabe )

To copy to clipboard, switch view to plain text mode 

When it crashes just check whether these adresses are different.

Do you do anything else (except for initialization and connections) with m_munPhRanges and m_munPkRanges? Maybe you delete them by accident?
