"Search" button crashes

[Anthony Liu]

Hi,

I tried to run qtmib on Ubuntu 12.10 x64.

Do you have Search working properly at your side? I tried trunk head and release 0.8.2, both share same issue.

I guess I should have missed installing something, if you could advise any direction to solve this, it would be great.

When I click "Search" on the main page, it crashes with the following log:

[RCP Team]

Thank you for the crash report. I think I have an uninitialized variable. In src/mainwindow.cpp can you please add one line

search_ = 0;

around line 39 in the file. The result should look something like this:

MainWindow::MainWindow(QWidget *parent): QMainWindow(parent) {
checkEnvironment();

search_ = 0; //<<<<<<< new line here
pref_ = 0;
createMenu();

I'll make a new release over the weekend.
