Comment 3 Maksim Orlovich 2009-09-24 19:54:36 UTC 
On that note, in  SearchBarPlugin::HTMLDocLoaded you should be using 
->document() and not ->htmlDocument(), since the latter will return a null node in case of XML, and then method accesses to it will throw an exception, aborting the program.

Probably the reporters are not building from source and cannot test your patch... Maybe you should just commit it (after considering comment 3)?

Note that bug 208039 looks like another duplicate.

Comment 24 Gerry Gavigan 2010-07-14 12:45:28 UTC 
Using 4.4.92 (openSUSE 11.2 RPMs) the search bar crashes silently when choosing one of the suggestions
Comment 25 Gerry Gavigan 2010-07-14 15:13:00 UTC 
Still there on 4.4.93 but it's only specific websites, specifically, searching on "information tribunal decisions" entering the phrase causes no problems ut choosing as a suggestion causes the silent crash

Comment 29 Dawit Alemayehu 2011-05-31 14:20:01 UTC 
This bug should not affect anything newer than KDE v4.6 since the searchbar plugin has been ported to use the new abstracted interface and no longer accesses the html engines directly anymore. If anyone can duplicate this on KDE v4.6 and up, feel free to reopen this report.
