Description Marcos Souza 2016-05-24 01:58:21 UTC 
I'm using Fedora 23, and the version of PCSXR is "svn" on the about dialog, so the version affected is the latest on Fedora repositories.

Version-Release number of selected component (if applicable):
SDL 2.0.4

Steps to Reproduce:
1. Plug an USB controller
2. Open PCSXR and click on Configure Controllers

Actual results:
Crash

Expected results:
Open window to map buttons of the controller

Additional info:

Comment 1 Philipp Wiesemann 2016-05-24 20:02:24 UTC 
SDL_JoystickName() should be called with an SDL_Joystick pointer in SDL 2.0.

The back trace looks like it was called with an integer. This is wrong.

The integer version is SDL_JoystickNameForIndex() in SDL 2.0.
Comment 2 Sam Lantinga 2017-08-12 02:21:40 UTC 
Looks like an application API error
