Small Qt application that crashes

If QWebView::findText() matches text that is in the document but not currently shown (the example code attached uses "overflow: hidden; text-overflow: ellipsis;") then the application will crash.

Stack trace:

#0  0x00007fff8e4d1cd8 in bzero$VARIANT$sse42 ()
#1  0x0000000101fe31ec in QVarLengthGlyphLayoutArray::QVarLengthGlyphLayoutArray ()
#2  0x0000000101fecd5a in QFontMetrics::width ()

The error seems to be due to the selection - it doesn't occur with QWebPage::HighlightAllOccurrences.
