I can verify the segfault exists on Debian. Here's a patch that I added to Debian's version to fix this problem.

Please, try to repeat with a newer version, 1.1.18 (http://dev.mysql.com/downloads/query-browser/1.1.html), and inform about the results.

I've tryed with the mysql-query-browser-1.1.18-1.i386.rpm, but the error still the same.

I can't reproduce this problem using 1.1.19.  Can you please try to reproduce it with the latest version ?

Thanks!

Sorry but in the download page, the latest version for Linux is the 1.1.18.1, where I'm wrong?

I get the same errors as reported in this bug report for Fedora Core 5, Test 3
This problem is defininity repeatable, at least on Fedora Core 5.

Some problems are noted:

1) To build Query-Browser v1.1.8-1, it required that GtkHtml v3.6
be available.  I had a newer version but it was not accepted.

2) GDB reported:

Comments say to get v1.1.9 release and try again but I am not able to obtain
this source code.  It is not accessable via your website as far as I can tell.
