Bug ID: 373763
Summary: Assertion failure with "View Diff"
Product: kdevplatform
Version: git master
Platform: Other
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: git
Assignee: kdevelop-bugs-n...@kde.org
Reporter: m...@flherne.uk
Target Milestone: ---
Using current master, adda66a
When selecting "Show Diff" or "Show Diff (all files)" in the annotations
context menu, or "Diff to previous revision" in the context menu of a commit in
the Git History dialog, KDevelop crashes with the backtrace below.
This seems to happen for any commit in any git project. Oopen
This doesn't happen with the "Show Differences" (i.e since latest commit) entry
in the Projects->Git context menu.
This didn't happen with 5.0.2.
ASSERT: "d->type==Special" in file
