More on this bug. KDE 4.1RC1, with a fresh install (rm -rf ~/.kde).
Today Dolphin just worked: hovering a PDF file produced the right preview into the information panel. Then I changed the current directory and tried to hover another PDF: then the crash triggered. After that crash, I launched Dolphin and moved to the first directory (the one in which every PDF preview worked well) and I got a crash when hovering the PDF!
I noted that the backtrace was different between the first crash and the following. The first time it crashed with:

Then the following time it always crashed with:
