Public bug reported: [Impact]
When editing a long one-line document with some markup (e.g. XML) with Pluma (or any other editor using gtksourceview2), you cannot delete a selected portion of text because the editor will crash. This has been reported upstream and fixed in [1], but the commit never made it to GTK+2 version of gtksourceview. So, I propose fixing it in current stable Ubuntu releases with the patch which fixes the crash for good. The debdiffs for every stable release are in the attachments below. [Test Case] Steps to reproduce: 1. Open a long one-line XML document (e.g. [2]) with Pluma. Any other editor using gtksourceview2 will also fit I think. 2. Select a portion of text. 3. Press Backspace (or Delete) key. 4. Pluma crashes. The full backtrace is at [3]. If you're running Pluma from the command-line, you'll notice a warning: GtkSourceView-CRITICAL **: Highlighting a single line took too much time, syntax highlighting will be disabled That's the key. The library tries to invalidate the region when text is deleted and the engine is disabled (i.e. syntax highlighting is off). [Regression Potential] After several months of testing the patch in Debian Jessie, I haven't noticed any regressions.
