Could you please attach the abrt backtrace here as well (with installed debuginfos) (if always reproducable) ? I just want to make sure that the error is not in ls itself (and coreutils package) ... The Kerneloops plugin for abrt gets this crash not the CCpp one. I don't know how to cause the Kerneloops plugin to include the debug info or how to steer the crash to the CCpp plugin. I deleted many files from that directory, there are now 47 items. Now ls doesn't crash the first time but produces a segment fault the second time it is invoked. now. CCpp plugin is run when kernel generates a coredump because of user space problem. In this case no user space problem was detected and no coredump was generated, so user space backtrace is not available. Created attachment 501275 [details]
