--- Begin Message ---Hi Brian! Here's another bug report: ----- Forwarded message from Jim Paris <[EMAIL PROTECTED]> ----- From: Jim Paris <[EMAIL PROTECTED]> Subject: Bug#345674: xfig: Crash when drawing arc from center point Date: Mon, 02 Jan 2006 13:09:27 -0500 Package: xfig Version: 1:3.2.5-alpha5-4 Severity: normal xfig crashes after drawing an arc starting with "center point" (middle button). It works fine if I draw an arc starting with "first point" (left button). Backtrace: Program received signal SIGSEGV, Segmentation fault. (gdb) bt 11 #0 0x000000000045b144 in ??
