Hello, I have the same problem. X server crashes every time a try to drag a component over the grid. I use xserver-xorg-video-radeonhd as a driver.
The X server gives this backtrace: Backtrace: 0: /usr/bin/X (xorg_backtrace+0x28) [0x4a0b88] 1: /usr/bin/X (0x400000+0x64259) [0x464259] 2: /lib/libpthread.so.0 (0x7ffbec237000+0xe990) [0x7ffbec245990] 3: /usr/lib/xorg/modules/libfb.so (fbBltOne+0x818) [0x7ffbe80c45e8] 4: /usr/lib/xorg/modules/libfb.so (fbPushFill+0x120) [0x7ffbe80ca840] 5: /usr/lib/xorg/modules/libfb.so (fbPushImage+0xf0) [0x7ffbe80caa30] 6: /usr/lib/xorg/modules/libfb.so (fbPushPixels+0x7b) [0x7ffbe80caadb] 7: /usr/bin/X (miPolyArc+0x2b47) [0x544307] 8: /usr/lib/xorg/modules/libfb.so (fbPolyArc+0x6d) [0x7ffbe80b8d2d] 9: /usr/lib/xorg/modules/libexa.so (0x7ffbe7e9e000+0x10071) [0x7ffbe7eae071] 10: /usr/bin/X (0x400000+0xd50db) [0x4d50db] 11: /usr/bin/X (0x400000+0x2ec10) [0x42ec10] 12: /usr/bin/X (0x400000+0x31584) [0x431584] 13: /usr/bin/X (0x400000+0x25bca) [0x425bca] 14: /lib/libc.so.6 (__libc_start_main+0xfd) [0x7ffbeab2babd] 15: /usr/bin/X (0x400000+0x25779) [0x425779] Segmentation fault at address (nil) Fatal server error: Caught signal 11 (Segmentation fault). Server aborting I have noticed that the error doesn't appear when I disable DRI (from xorg.conf settings). I am note sure that this is a qucs bug and not a radeonhd (or a libgl1-mesa-dri) one. If so please inform me in order to report the problem there. Thanks. __________________________________________________ Χρησιμοποιείτε Yahoo!; Βαρεθήκατε τα ενοχλητικά μηνύματα (spam); Το Yahoo!
