+How to submit a good bug report?
+
+First you should give the following information:
+ - irssi version, if CVS (or devel. tarball) then which day?
+ - operating system / distribution and it's version
+ - when did it crash? did you do something? can you reproduce the crash?
+
+Getting backtrace of the crash also helps a lot, especially if irssi crashes
+randomly. If after crash you see text:
+
+ "segmentation fault (core dumped)"
+
+It writes a file named "core" to directory where you started irssi. If it
+doesn't print the "(core dumped)" or you can't find the core file, you'll
+have to raise the limit for max. core file size before running irssi. To
+do this, say:
+
+ ulimit -c unlimited
+
+So, if you have the core file and GNU debugger (gdb), you can get the
+backtrace with:
+
+ gdb irssi core
+ bt
+
+Paste all the lines starting from line having #0 at the beginning.
+
+Here's an example session:
+
+[cras@hurina] ~/cvs/m/irssi/src/fe-text$ gdb ./irssi core
