Does literally any text you type into the search field cause it to crash, or only some text? 2. Are you using your system in a language that's not English? If so, does the crashing stop if you switch to English?

Got another report with the same backtrace from someone also using Plasma with a non-English language; re-opening. Vasua, does the crash go away if you temporarily switch the system language to English?
(In reply to Nate Graham from comment #5) > Got another report with the same backtrace from someone also using Plasma > with a non-English language; re-opening. > > Vasua, does the crash go away if you temporarily switch the system language > to English? Not the original reporter, but I cannot reproduce this with my System language set to Tamil or Ukrainian, so I guess something else might also be needed to reproduce this. I tried typing both Tamil and Latin text. Operating System: KDE neon Unstable Edition KDE Plasma version: 5.25.80 Kde frameworks version: 5.96.0 Qt version: 5.15.4 Kernel: 5.13.0-51-generic (64-bit) Graphics: X11
for (const auto &keyword : keywords) { if (keyword.startsWith(pattern, Qt::CaseInsensitive)) { return true; } } > Seems like maybe keywords is empty, as right now we are assuming it's not. That can't be it. If keywords was empty none of the loop body would have run. And since from the trace it got into QString code means there was some QString there which it operated on. The crash is somehow happening in Qt's string comparison code itself. Maybe some invalid Unicode somewhere. It would be nice to have the actual values of the strings being compared, if someone can use GDB to get that.
