Description Leonard Lausen 2017-12-22 10:08:22 UTC 
Application: plasmashell (5.11.4)
 (Compiled from sources)

Frameworks Version: 5.41.0
Operating System: Linux 4.14.7-gentoo x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
- What I was doing when the application crashed:

Open the application launcher via shortcut / mouse and start typing to retrieve search result (application / desktop action). Sometimes the plasma desktop crashes during the typing or keyboard navigation in the results list.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

Comment 1 Christoph Feck 2017-12-23 00:53:58 UTC 
Crash is in libsqlite3. Please report this issue to libsqlite3 developers.
Comment 2 Leonard Lausen 2018-01-19 07:49:27 UTC 
How confident are you Christoph that the problem is not part of plasmashell? I received the following reply on the sqlite mailinglist:

> These kinds of things are almost always the result of heap
> corruption in the application.  In other words, there is nothing wrong
> with SQLite.  SQLite just happened to be the unlucky victim to first
> stumble over the corrupted heap.  In fact, we find that whenever there
> is heap corruption of any sort, SQLite is more likely that most other
> libraries to be the first to stumble into it.
