In Krusader 2.6.0 under Manjaro Linux, when I hit NumPad * for quick search (e.g. to start searching for *.jpg), not only Krusader but the whole system becomes unresponsive, occupying all the CPU and memory resources at the same time.
Thanks for reporting. Confirmed. However, this is not related to quicksearch or numpad. When the details view gets a key press event with an asterisk, it is redirected to QTreeView which runs a nasty while loop endlessly. See https://code.woboq.org/qt5/qtbase/src/widgets/itemviews/qtreeview.cpp.html#1989 The bug is there for at least a year. Fix is an one-liner. You want to start the quick search by pressing "*" on numpad (=> adds KeypadModifier to event in Qt). This doesn't work right now but I can fix it too.
