qcollectiongenerator: need remove cache file prior to Assistant start
Steps to reproduce / test case
0) Follow the "simpletextviewer" example.
1) Do 'qcollectiongenerator doc.qhcp -o doc.qhc'
2) Run '.../Assistant -collectionFile doc.qhc'
3) It works.
4) Quit Assistant.
5) Re-start Assistant ... all is still okay.
6) Quit Assistant.
7) Change some docs content (or edit doc.qhcp or edit doc.qhp)
8) Do 'qcollectiongenerator doc.qhcp -o doc.qhc'
9) Run '.../Assistant -collectionFile doc.qhc'
10) It starts, but then crashes soon after display. Issues "Bus error" to the terminal and see attached Assistant.crash.log.gz
11) Remove the copy of doc.qhc from cacheDirectory in QDesktopServices::DataLocation (or if not using cacheDirectory element in doc.qhcp file, then remove ${QDesktopServices::DataLocation}/Trolltech/Assistant/doc.qhc)
12) Re-start Assistant ... all is now okay.
13) Subsequent edits of content and re-run of qcollectiongenerator then Assistant will be okay only if that copy of doc.qhc is removed before starting Assistant.
