Hi: it is my first time in this list. I have found that some kde programs in my system (Fedora 1) are very easy to produce segment default. The affected programs now are kdevelop2 ( just apt from the official source) and kile-1.6.1. In fact, at first they worked ok. But after sometime, they could not be started. If run in console, it said Segment Default. So, in order to use them, i have to re install the rpm either use rpm -e and rpm -i or use rpm -U --force. Then they can start again. However, after sometime ( i really dont know when), they will fail again. :-( so i have to the reintall again. One thing i can be sure is that after each re-installation, they surely can be started. Does anybody have the same experience ? Any expert tell me why and how to solve ? I dont want to keep the rpms in my home dir in order to reinstall them that often. Thanks very much climb
