I finished what I was working on and closed kwallet. On the desktop where I opened kwallet, there was still an entry in the task manager with Kwallet, but preview just showed a small box, no actual window, and when I right clicked it, Plasma crashed. -- Backtrace: Application: Plasma Desktop Shell (kdeinit4), signal: Segmentation fault [Current thread is 1 (Thread 0x7f7c5032d760 (LWP 2389))] Thread 3 (Thread 0x7f7c33078700 (LWP 2390)): #0 0x00007f7c4ec1d38c in pthread_cond_wait@@GLIBC_2.3.2 () from /lib64/libpthread.so.0 #1 0x00007f7c440b6064 in QTWTF::TCMalloc_PageHeap::scavengerThread (this=0x7f7c443cf180) at ../3rdparty/javascriptcore/JavaScriptCore/wtf/FastMalloc.cpp:2359 #2 0x00007f7c440b6099 in QTWTF::TCMalloc_PageHeap::runScavengerThread (context=0x7f7c443dd254) at ../3rdparty/javascriptcore/JavaScriptCore/wtf/FastMalloc.cpp:1464 #3 0x00007f7c413fe9e3 in ??
