Application: kate (3.7.1) KDE Platform Version: 4.7.1 (4.7.1) Qt Version: 4.7.4 Operating System: Linux 3.0.0-12-generic x86_64 Distribution: Ubuntu 11.10 -- Information about the crash: I tried to open a large log file (> 140 MiB) and Kate crashed every time with the given segfault. Perhaps that has something to do with the log file as it contains no newline... only a 140 MiB line of characters. The crash can be reproduced every time. -- Backtrace: Application: Kate (kate), signal: Segmentation fault [Current thread is 1 (Thread 0x7fb8ca00e780 (LWP 11635))] Thread 2 (Thread 0x7fb8b80cc700 (LWP 11636)): #0 pthread_cond_wait@@GLIBC_2.3.2 () at ../nptl/sysdeps/unix/sysv/linux/x86_64/pthread_cond_wait.S:162 #1 0x00007fb8b8fc3fe2 in ??

Reported using DrKonqi
Qt doesn't like multi-thousand column lines for layouting. Current Kate master just limits the lines to some threshold and hard wraps on load.
I can reproduce it with Kate 20.12.
Please do not reopen ancient bugs. Instead, report a new ticket with a current backtrace.
If I opened a new ticket right away, it would have been closed as a duplicate; will do now.
