Hello, I received also a crash [3] when using kaffeine with a DVB-S stick and trying after a scan new found channels.
The crash in [1] looks similar. I opened an upstream merge request [2] to fix usage of std::prev, which returns currently one element after end(), not the element before end() and therefore crashes. Kind regards, Bernhard [1] https://bugs.kde.org/show_bug.cgi?id=505497 [2] https://invent.kde.org/multimedia/kaffeine/-/merge_requests/23 [3] Program terminated with signal SIGSEGV, Segmentation fault. #0 SqlInterface::sqlFindFreeKey<QMap<SqlKey, ExplicitlySharedDataPointer<DvbChannel const> > > (this=<optimized out>, container=...) at /usr/include/c++/14/bits/stl_iterator_base_funcs.h:175 175 while (__n--) [Current thread is 1 (Thread 0x7fc6a0915040 (LWP 2453962))] (gdb) bt #0 SqlInterface::sqlFindFreeKey<QMap<SqlKey, ExplicitlySharedDataPointer<DvbChannel const> > > (this=<optimized out>, container=...) at /usr/include/c++/14/bits/stl_iterator_base_funcs.h:175 #1 DvbChannelModel::addChannel (this=this@entry=0x557886ca9730, channel=...) at ./src/dvb/dvbchannel.cpp:376 #2 0x00005578795cb83b in DvbChannelModel::cloneFrom (this=0x557886ca9730, other=<optimized out>) at ./src/dvb/dvbchannel.cpp:300 #3 0x000055787963f8d9 in DvbScanDialog::dialogAccepted (this=0x7fc698002690) at ./src/dvb/dvbscandialog.cpp:488 #4 0x00007fc6a551893e in ??
