Searching works perfectly fine from the glib demo so i'd say there's something wrong in the zhatura code, having a look at the crashes i get it seems that the zathura code is accessing poppler from two different threads (which is not yet supported). We'd need to speak with someone that can confirm or unconfirm my hyphotesys, so can you please ask the zatuhra developer to come here and answer my question? I opened an new issue with the zathura developers, asking them to come and answer your question(s). (http://bugs.pwmt.org/issue253) The zathura developers solved the bug, thanks for your input! |

Created attachment 66539 [details] pdf that gives the problem When looking at a (specific) pdf file with zathura, searching for text gave a segfault. This is reproducible but seemingly occurs random after searching for a few word. I traced this back to poppler, backtrace from gdb: Program received signal SIGSEGV, Segmentation fault. 0x00007fffeb6ef217 in TextPage::findText (this=0x960240, s=<optimized out>, len=6, startAtTop=false, stopAtBottom=true, startAtLast=<optimized out>, stopAtLast=false, caseSensitive=false, backward=false, wholeWord=false, xMin=0x7fffffffb390, yMin=0x7fffffffb398, xMax=0x7fffffffb3a0, yMax=0x7fffffffb3a8) at TextOutputDev.cc:3598 3598 blk = blocks[i]; (gdb) bt #0 0x00007fffeb6ef217 in TextPage::findText (this=0x960240, s=<optimized out>, len=6, startAtTop=false, stopAtBottom=true, startAtLast=<optimized out>, stopAtLast=false, caseSensitive=false, backward=false, wholeWord=false, xMin=0x7fffffffb390, yMin=0x7fffffffb398, xMax=0x7fffffffb3a0, yMax=0x7fffffffb3a8) at TextOutputDev.cc:3598 #1 0x00007fffeb9f6082 in poppler_page_find_text (page=<optimized out>, text=<optimized out>) at poppler-page.cc:886 #2 0x00007fffebc3b017 in pdf_page_search_text () from /usr/lib/zathura/pdf.so #3 0x0000000000415c3f in cmd_search () ... When I print the address of 'blocks', it gives 0x0, so I guess that's the culprit... grtz Steven
