Bug 312845 – ASSERT(partialRun.length < trailingInlineTextItem.length()) when opening linkedin.com/feed

• Status: RESOLVED
• Resolution: DUPLICATE
• Component: Layout and Rendering

[Jean-Yves Avenard [:jya]]

In Minibrowser debug build.

1- Open LinkedIn.com and login.
this goes to https://www.linkedin.com/feed/

2- Go to settings  -> Set current URL to default URLs

3- Quit MiniBrowser, start Minibrowser

You will always hit the assertion:

`ASSERT(partialRun.length < trailingInlineTextItem.length());`
in LineBuilder::processLineBreakingResult

step 2&3 aren't compulsory, I got the assert regardless.
