After some experiments I have found the solution. I'm really very amused with the result. The lyx crashed X's after inserting the PS picture only when I've set the screen fonts to ISO-8859-2. I've checked the ISO-8859-2 font directories on my box and stated that "fonts.dir" does not exist in some of them - so the X server wasn't able to find some fonts. Running mkfontdir fixed all the problems. Well, but one problem still exists! Why lack of some fonts causes X server to crash instead of using other available fonts, or crashing only the process trying to use unavailable fonts? It seems to me that this is a serious bug in XFree86 3.3 :-(. I have experienced similar problems with Netscape, and now I think that the reason was the same - unavailable fonts in ISO-8859-2.
